Antimony trioxide has been used as a white pigment since ancient times. The pigmentation from antimony oxide in plastics can be controlled and adjusted by the judicious selection of a Sb 2 O 3 grade having a specific particle size. The product with the smallest particle size and the narrowest particle-size range imparts the whitest color and highest opacity.
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 conditions.

form of antimony in drinking-water is a key determinant of the toxicity, and it would appear that antimony leached from antimony-containing materials would be in the form of the antimony(V) oxo-anion, which is the less toxic form. The subchronic tox-icity of antimony trioxide is lower than that of potassium antimony tartrate, which is

The process uses a small reverberatory furnace at about 650 °C operating in batch or continuous mode, or a batch pan. The oxidation product is a lead–antimony–arsenic–tin oxide slag that is then reduced in another reverberatory furnace or short rotary furnace to make antimonial lead alloys; arsenical fume is processed separately.
crude antimony trioxide rotary furnace thebathroomcompany.nl. Revolatilizing of crude antimony(III) oxide. Step 1) Crude stibnite is oxidized to crude antimony(III) oxide using furnaces operating at approximately 500 to 1,000 °C. The reaction is the following: 2 Sb 2 S 3 + 9 O 2 → 2 Sb 2 O 3 + 6 SO 2.
Antimony trioxide may be volatilized from sulfide ores, and can be reduced to metal with charcoal in reverberatory furnaces. Antimony product may also be produced by blast furnace smelting or hydrometallurgical methods. China is the world's largest producer of antimony.
* Antimony Trioxide may damage the kidneys, liver and heart. IDENTIFICATION Antimony Trioxide is a white, odorless crystalline (sand-like) powder. It is used as a flame-proofing agent, in pigments and ceramics, to stain iron and copper, and to decolorize glass. REASON FOR CITATION * Antimony Trioxide is on the Hazardous Substance List

Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.
