Antimon(III)-oxid (auch Antimontrioxid genannt) ist eine Antimonverbindung mit der Summenformel Sb2O3. During the first few cycles, Sb2O3 and Sb2O5 cause an abrupt rise in electrode capacity. [11], Internationale Agentur für Krebsforschung, Schweizerische Unfallversicherungsanstalt, Bromierte Flammschutzmittel in Elektro- und Elektronikgeräten: Das Flammschutzmittel Decabromdiphenylether (DecaBDE) ist durch umweltverträglichere Alternativen ersetzbar, https://de.wikipedia.org/w/index.php?title=Antimon(III)-oxid&oldid=204922578, Stoff mit Verdacht auf krebserzeugende Wirkung, Wikipedia:Vom Gesetzgeber eingestufter Gefahrstoff, „Creative Commons Attribution/Share Alike“. High‐quality, crystalline SnO 2 films are deposited via decomposition of metal precursors sprayed directly onto hot (>400 °C) substrates. IDENTIFICATION. Water content in the anodic layer (measured in microliters of water per gram of sample), formed at +1.50 V potentiostatic polarization on flat electrodes, as a function of antimony content in the alloy [34]. *Please select more than one item to compare Its chemical formula is Sb 2 O 3. It follows, therefore, that the valency of antimony also plays a role in the processes of building up the structure of PAM. The largest use of antimony oxide is in a synergistic flame retardant system for plastics and textiles. The data in Table 10.3 evidence that Sb2O5 is more hydrated than Sb2O3. The use of antimony as a flame retardant in plastic products nowadays plays a major role in the antimony processing industry with antimony trioxide (also called antimony white) accounting for over 70% of today’s worldwide antimony consumption. Similar properties are exhibited by tin, bismuth, and probably other metal ions as well (see Fig. The annual consumption of antimony(III) oxide in the United States and Europe is approximately 10,000 and 25,000 tonnes, respectively. This substance is used in the following areas: scientific research and development. Antimony is released into the environment from natural sources and industry. Widespread uses by professional workers This substance is used in the following products: adhesives and sealants, coating products, inks and toners, polymers, textile treatment products and dyes, pH regulators and water treatment products, lubricants and greases and paper chemicals and dyes. Two tubular electrodes of each type were set to cycling so that the powders would be formed to active masses. Here, a detailed investigation on the synthesis of antimony‐doped tin oxide films using an ultrasonic spray coating system is presented. Die Neubewertung läuft seit 2018 und wird von Deutschland durchgeführt. EC Number 215-237-7. Antimony trioxide is a chemical used in the manufacture of some polyethylene terephthalate (PET) plastic, which is used to make food and beverage containers. Most probably, these ions enter the gel zones of the particles and contribute to binding the polymer chains to one another. Flame-retardant compounds used in the manufacture of conveyor belts, such as. Antimon [antiˈmoːn] (von lateinisch Antimonium, vermutlich von arabisch al-ithmîd(un) (ithmid / إثمد / iṯmid, Antimonsulfid bzw. The water content of some of the commercially available lead and antimony oxides was determined and the obtained results are presented in Table 10.3 [34]. These oxides have a similar effect to that of antimony added to the grid alloy. Most sensitive to these changes are the regions near the CL/PAM interface. Antimony is also used for pigments in plastics, paints, rubber, and for a wide variety of minor uses, including medicines, fireworks and others. The test for flame resistance is the SSFT as mentioned in preceding sections. It is therefore appropriate to term these dopants “binders.” Binders support the polymer chains and prevent the polymer network from disintegration on decrease of the PAM density. Antimony oxide is added to textiles and plastics to prevent them from catching fire. Figure 13.3 shows the SSFT used to test for the flame resistance of conveyor belts. Xikuangshan Mine in Hunan province has the largest deposits in China with an estimated deposit of 2.1 million metric tons. Antimony trioxide, also known as antimony(III) oxide, is a chemical compound.

Antimony oxide is added to textiles and plastics to prevent them from catching fire and is also used in paints (especially enamels), ceramics, and fireworks. These are based on magnesium hydroxide and aluminum hydroxide. Antimony is considered to be a “strategic metal” and wartime applications include antimony oxide used as a flame retardant in plastics and textiles for vehicles and aircraft, antimony metal used in storage batteries and in ordnance to harden lead, and antimony tri-sulfide for primers in ordnance and rockets.. Antimony trioxide is a white solid. Chemically obtained PbO2 contains far less water than the electrochemically obtained oxide. It has low electrochemical activity. Trivalent antimony oxide also has other uses. 2005-03-27. Periode und der 5. The above experimental data indicate that the alloy composition plays an important role during the formation processes as it determines the conductivity of the PAM layer that is in contact with the corrosion layer. Owing to their good electrical properties, antimony tin oxide has the ability to form nano particles which are further used in a wide variety of applications such as alloys and composites. 4.23). Ursächlich für die Aufnahme von Antimon(III)-oxid waren die Besorgnisse bezüglich Exposition von Arbeitnehmern, hoher (aggregierter) Tonnage, hohes Risikoverhältnis (Risk Characterisation Ratio, RCR), anderer Exposition/risikobasierter Bedenken und weit verbreiteter Verwendung sowie der vermuteten Gefahren durch krebserregende Eigenschaften. However, it does not have flame retarding properties itself; instead, it is a synergist for halogenated flame retardants in plastics, paints, adhesives, sealants, rubber, and textile back-coatings. Typically, a higher purity grade is used for this purpose. Bei Flammschutzmitteln wie Decabromdiphenylether wird Antimontrioxid als Synergist eingesetzt. The same flame test and criteria for flame resistance is applied to these materials as for conveyor belts. 9680.12 Date of Preparation: 3/3/97 Revision: 8/3/15 Section 1 - Chemical Product and Company Identification Product/Chemical Name: Antimony Oxide Synonyms: Antimony white, Antimony Trioxide H General Use: FFire retardant Restrictions on use: None Manufacturer: Marshall Additive Technologies The metal can also be obtained by conversion of stibnite to the oxide, followed by reduction with carbon.Sodium sulfide solutions are effective leaching agents for the concentration of stibnite from ores. Hauptgruppe, bzw. Fig. Hierbei werden die Auswirkungen des Stoffs auf die menschliche Gesundheit bzw. Another option is to use the same filler systems which are used in polyethylene insulated cables and wires. Antimony is a component of many lead and tin alloys, which are important materials for making bearings and solders. The main application is as flame retardant synergist in combination with halogenated materials. Es wird auch als Katalysator für die Herstellung von PET verwendet. 6 Chemical Vendors. This happens on plate cycling. 10.29 presents the specific capacity/cycle number curves for the three types of electrodes under test [38]. The formulation for these items can also be different. Antimony is a naturally occurring metal often used in combination with lead and zinc, found in metal alloys, paints, ceramics, and fireworks. It … Antimony Trioxide Nanopowder. Antimontrioxid ist ein weißes kristallines Pulver, das in Wasser unlöslich ist, sich aber in konzentrierten Säuren und Laugen löst. NACRES NA.22 Antimony oxide is found in nature as the minerals valentinite and senarmontite and is the most significant commercial compound of antimony. Antimony ions have high affinity toward water (Table 10.3). 3 Chemical and Physical Properties Expand this section. Es gehört zur Stoffklasse der Oxide. Antimony is also used for pigments in plastics, paints, rubber, and for a wide variety of minor uses, including medicines, fireworks and others.Antimony oxide is a brilliant yellow color, accounting for much of the pigment use.A tiny amount of highly purified antimony metal is used in the computer industry to make semiconductors. Polymer chains of PbO2 particles and agglomerates, on the other hand, are hydrated. Metallic antimony is not affected by air or moisture under ordinary conditions, but it is gradually converted to an oxide if the air is moist. Tubular electrodes were filled with the above two mixtures (PbO2 + Sb2O3 or PbO2 + Sb2O5). Consequently, antimony ions would be readily bonded to hydrated polymer chains to form a polymer network. MDL number MFCD00011216. PubChem Substance ID 24855500. Probably, the higher affinity to hydration of Sb2O5 as compared to Sb2O3 contributes to the more beneficial effect of Sb2O5. Uses at industrial sites ECHA has no public registered data indicating whether or in which chemical products the substance might be used. Components such as conveyor belt roller covers, belt scrapers and lagging material for use on belt drives are constructed in a different manner than conveyor belts. 1907/2006 (REACH) im Rahmen der Stoffbewertung in den fortlaufenden Aktionsplan der Gemeinschaft (CoRAP) aufgenommen.

Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. When there is no binder, the polymer network exhibits high conductivity only with a high density of polymer chains in the gel. todiniandco.com. More... Molecular Weight: 291.52 g/mol. In the air, antimony attaches to very small particles that may stay there for many days. Commercial production and uses. For example, belt scraper material may be made from hard plastic which is shaped in a manner to remove debris from a conveyor belt. This hypothesis was verified through oxidation of Pb–Sb alloys with different content of antimony and determining the water content in the anodic PbO2 layer formed. The British Geological Survey (BGS) reported that in 2005 China was the top producer of antimony with approximately 84% of the world share, followed at a distance by South Africa, Bolivia and Tajikistan. It is sometimes used with other More details on conveyor belts and their construction may be found in the Rubber Manufacturers Association Handbook (RMA, 1989). Flame-retardant compounds used in the manufacture of conveyor belts, such as antimony oxide, enhance the ability of conveyor belts to pass the required flame test.

A conveyor belt may be made from polyvinyl chloride and fabric such as polyester or styrene-butadiene rubber and several layers of polyester or nylon fabric. Antimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. Antimony oxide is being used as flame retardant in increasing quantities. Wie die Löslichkeit in konzentrierten Säuren – wobei je nach Säurekonzentration neutrale Salze oder Oxidsalze entstehen – und in Laugen – wobei sich Antimonite bilden – zeigt, handelt es sich bei Antimontrioxid um ein amphoteres Oxid. Copyright © 2020 Elsevier B.V. or its licensors or contributors. die Umwelt neu bewertet und ggf. Antimony Oxide MSDS No. It has antimony and oxide ions in it. 10.27 [34]. Contents. The obtained results of these investigations are presented in Fig. The major use of Antimony Oxide is as a Flame Retardant synergist in plastics, rubber, textiles, adhesives, fiberglass & Paper. Such flame retardants are found in electrical apparatuses, textiles, leather, and coatings. These results indicate that antimony increases the degree of amorphization of the PbO2 layer, which is also confirmed by the XRD data for the anodic layer [34]. The higher the antimony content in the alloy, the higher the degree of hydration of the corrosion layer obtained, i.e., the volume of the gel zones in the lead dioxide layer increases due to incorporation of antimony ions in its structure. Among them, commonly used additives are additive brominated hydrocarbons and reactive brominated hydrocarbons, nonhalogenated phosphate esters, halogenated phosphate esters, trioxide, Two of three contain chlorine which gives them substantial fire retarding properties. These include ovenproof or microwavable plastic trays, as well as some plastic water bottles. In der Galvanik dient es zum Antimonieren anderer Metalle. The same effect is also observed when the concentration of binders in the gel is low. Es entspricht in seiner Struktur dem Phosphortrioxid. A third type of electrodes were filled with the ground PAM powder only with no addition of antimony oxide. 2 Names and Identifiers Expand this section. Molecular Weight 323.52 .
