what is antimony trioxide used for

Antimony Trioxide Market: Dynamics . Immediate steps should be taken to limit its spread to the environment. Antimony trioxide does not reacts directly as a flame retardant but is used as a synergist to enhance the activity of halogenated flame-retardants. Antimony trioxide can also be used as a catalyst in the formation of polyethylene terephthalate. Antimony trioxide (ATO) is commonly used as a co-synergist with halogenated flame retardants to enhance their effectiveness. 3 Chemical and Physical Properties Expand this section. Antimony(III) oxide has suspected carcinogenic potential for humans. Any industries use antimony as a flame retardant synergist including but not limited to the plastics, textiles, rubber, paper, and paint industries. The antimony is separated and used. No other human health hazards were identified for antimony(III) oxide, and no risks to human health and the environment were identified from the production and use of antimony trioxide in daily life. A dose of 50mg/m 3 of antimony is fatal for humans. Babbit metals, used for machinery bearings, are alloys of lead, tin, copper and antimony. Antimony does not react with hydrochloric acid in the absence of oxygen. Antimony Trioxide are used as synergists to enhance the activity of halogenated flame-retardants by stepwise releasing the halogenated radicals to retard gas phase chain reaction of flame spread. Antimony trioxide is also used as a flocculent in the production of titanium dioxide. When heated, antimony reacts with oxygen in air forming Sb 2 O 3. The primary hazard is the threat to the environment. The flame is bluish white. Porcelain and Enameling services use it as an opacifier. Examples are: - Insulation bodies - Hoods for electrics, electronics and connectors - Reactive component in plastics for laser printing (durability and legibility of laser printings are product safety relevant – e.g. Health Dangers of Antimony. ANTIMONY TRIOXIDE: ICSC: 0012: Antimony sesquioxide Antimony(III) oxide Antimony white Flowers of antimony CI 77052 C.I. AkzoNobel has decided to add antimony trioxide (ATO) to its list of restricted substances, limiting the levels permitted in the company’s products, dependent on factors such as solvent dispersion, product type and end use. Gap uses it in clothing of all types. How is it used? Antimony trioxide is used as a synergist to enhance the activity of the halogenated flame retardant. This condition may occur within 1 days to 2 months after you start taking arsenic trioxide. 4 Spectral Information Expand this section. Antimony is used as a part of the therapy for these conditions and can sometimes have toxic side effects that lead to pancreatitis and cardio toxicity. Modern uses of Antimony also take advantage of its hardening effect in alloys. It is insoluble in water. Antimony trioxide is an amphoteric oxide, dissolving in alkaline solution to give antimonites and in acid solution to given a range of polyantimonous acids. 1 Structures Expand this section. The product with the smallest particle size and the narrowest particle-size range imparts the whitest color and highest opacity. The subcommittee used that information to characterize the health risk from exposure to antimony trioxide. ANTIMONY TRIOXIDE 229 10 Antimony Trioxide THIS chapter reviews the physical and chemical properties, toxicokinetics, toxicological, epidemiological, and exposure data on antimony trioxide. The viscosity level of these white antimony trioxide sb2o3 is extremely high, however, it can be diluted with other solutions very easily. Antimony trioxide (ATO) is commonly used as a cosynergist with halogenated flame retardants to enhance their effectiveness. Prolonged dermal exposure to antimony dust can lead to damage and infection of the skin. Antimony trioxide is a white crystalline solid. Its TLV is 0.5 mg/m 3, as for most antimony compounds. The annual consumption of antimony trioxide in the United States and Europe is approximately 10,000 and 25,000 tonnes, respectively.The main application is for flame retardants in combination with halogenated materials. The Oeko-Institut has recommended against a restriction of antimony trioxide (ATO) in electrical and electronic equipment under the EU’s Restriction of Hazardous Substances (RoHS) directive. Antimony Trioxide Nanopowder. The antimony trioxide is then heated with carbon to make carbon dioxide and antimony. You can also find tin antimony solder. Contents. These white antimony trioxide sb2o3 are also available in the form of MgO nanopowder that is widely used in numerous heating, agricultural, industrial, and electronic solutions. Reaction of antimony with air. Antimony is a semi-metallic chemical element that can exist in two forms: the metallic form which is shiny, silvery, hard and brittle; and the non-metallic form which is a grey powder. Important Information. 5 Related Records Expand this section. Many industries use antimony as a flame retardant synergist including but not limited to the plastics, textiles, rubber, paper, and paint industries. Antimony compounds (especially the trioxide) are widely used as flame retardants in paints, plastics, rubber, and textiles. Flame retardants used in household items such as mattress covers, furniture and carpets may contain antimony trioxide. Create . Antimony is a mineral that has been known since ancient times. Antimony Trioxide is often combined with halogenated compounds when used as a flame retardant, without antimony trioxide, about twice as much halogenated compound would be required to produce an effective flame retardant. The information is aggregated from the data coming from REACH substance registrations provided by … Where I can view product specification or MSDS of Antimony Trioxide? Immediate steps should be taken to limit its spread to the environment. Antimony is a regulated contaminant that poses both acute and chronic health effects in drinking water. Isotopes of Antimony. Uses. In general, how your body reacts to a toxic level of antimony will depend on how you were exposed. In the absence of antimony trioxide about twice as much halogenated compound would be needed to reach the same level of flame retardancy. antimony trioxide price solutions are extremely important for distinct industries to serve a variety of multiple purposes. (8) Antimony is used in the semiconductor industry as an n-type dopant for silicon. Another way to make antimony is to heat stibnite with scrap iron. In addition, Antimony Trioxide can be used as an opacifying agent for glasses, ceramics and enamels and in it can be found in specialty pigments. The combination of the halides and the antimony being key to the flame-retardant action for polymers, helping to form less flammable chars. Antimony trioxide has been used as a white pigment since ancient times. Antimony is also used as an alloy in solder. 6 Chemical Vendors. It is a bad conductor of heat and electricity, is stable in dry air and is not attacked by dilute acids or alkalis. Recent comprehensive genotoxicity studies and a critical review by the European Commission have indicated that, contrary to the indications of earlier less well authenticated studies, antimony trioxide is not a genotoxic carcinogen. In powdered form, antimony is explosive and can lead to spontaneous ignition when exposed to air. Previous reports suggest that polyethylene terephthalate (PET) plastics used for water bottles in Europe and Canada leach antimony, but no studies on bottled water in the United States have previously been conducted. 2019 antimony Day – Spotlight on Regulation Takeaways in the formation of polyethylene terephthalate antimony oxide as!
