IRIS Summary (PDF) (21 pp, 158 K) Key IRIS Values; Other EPA Elemental antimony oxidises slowly in moist air to form a mixture of antimony and antimony oxide and burns in air to form antimony trioxide vapour. Pentavalent antimony is an oxidising agent. Historically, the systemic administration of antimony compounds has been used in the treatment of many conditions including syphilis, whooping cough and gout and topical antimony compounds were believed

USAC Antimony Metal and Antimony Oxide

Antimony trioxide has two crystalline forms, either senarmontite which is cubic, or valentinite which is orthorhombic. Antimony trioxide (Sb 2 0 3) has a molecular weight of 291.52, a melting point of 656 C, a boiling point of 1,425 C, and a refractive index of 2.087. Montana Brand antimony oxides are formed exclusively by the sublimation of antimony metal under extremely rigid furnace

Antimony (Sb) is an element in the group XV that has allotropic modifications and two main oxidation states as Sb(III) and Sb(V) in nature. Antimony is a pollutant of concern for its carcinogenic and bioaccumulation effects. Sb presence in drinking water or wastewater is strictly regulated worldwide. Removing Sb(V) from water is a challenging task. In this study, we aim to develop a simple

Antimony trioxide is released into the Canadian environment mainly as a result of its use as a synergistic flame retardant and as atmospheric emissions from fossil fuel combustion and non-ferrous metal production. Antimony trioxide emitted to air is then deposited onto surrounding terrestrial and aquatic ecosystems. Because antimony trioxide has some solubility in water, it will dissolve in

Biomonitoring Summary. Related Pages. Antimony. CAS No. 7440-36-0. General Information. Antimony is found in ores or other minerals, often combined with oxygen to form antimony trioxide or with sulfur to form stibnite. Antimony can exist in one of four valences in its various chemical and physical forms: -3, 0, +3, and +5. It is used in metal alloys, storage batteries, solder, sheet and pipe

Antimony Trioxide, Sb 2 O 3 was known in ancient times; it is probably referred to by Pliny under the name of stibia femina, and by Basil Valentine under the name flores Antimonii. The latter name was subsequently applied to the product derived from the roasting of antimony sulphide. Antimony trioxide occurs naturally in the minerals senarmontite and valentinite, and in certain other more

Antimony trioxide can also be made by a two step process. Stibnite is burned in air with calcium chloride to make calcium sulfate and antimony trichloride, which is reacted with water to make antimony trioxide. Uses. Antimony trioxide is mainly used as a flame retardant. Business offer. Antimony pollution in China ScienceDirect. 1. Introduction. Antimony (Sb) is a metalloid belonging to Group

Antimony trioxide (Sb2O3) is used to make flame- proofing materials. Antimony sulfide (Sb2S3) is widely used in safety matches, military ammunition, explosives and fireworks. Stanford Advanced Materials (SAM) now can provide antimony metal and antimony compounds including: Antimony Metal: Shapes: ingot, powder, lump, particle; Purity: 2N-7N, or customized.

21.01.2015This Public Health Statement is the summary chapter from the Toxicological Profile for antimony. It is one in a series of Public Health Statements about hazardous substances and their health effects. A shorter version, the ToxFAQs™, is also available. This information is important because this substance may harm you. The effects of exposure to any hazardous substance depend on the dose,

The price range for high-tint antimony trioxide, published by American Metal Market, was $0.90 to $1.05 per pound at the start of the year and $0.89 to $1.25 per pound at the end of the year. Trade Imports of antimony were, as is usually the case, much larger than exports—about five-fold larger in 2000 (tables 5-8). Imports rose slightly, with the categories of ore/concentrate and oxide
