Antimony trioxide
Chemical formula or structure: Sb2O3
Composition and content: Sb2O3 99.80 or more
CAS NO. :1309-64-4
TSCA NO. :1309-64-4
EINECS NO. :215-175-0
United Nations Category: 6.3
UN number: 1549 (As 0.5% or less, so do not belong to dangerous goods)
Uses: This product is a white fine powder of cubic crystal. Products as a flame retardant synergist is widely used in plastics, textile, chemical fiber, and in pigments, paints, electronics, enamel, glass, plastic resins, synthetic fibers, synthetic rubber, cables and other materials, as flame retardant additives and synergists. Chemical manufacturing and other industries are widely used.
Description: Antimony molecular weight 291.50, density 5.2g/cm3, melting point 656 ℃, boiling point 1425 ℃, 400 ℃, high vacuum can be sublimated. Slightly soluble in water, dilute sulfuric acid, nitric acid, dissolved in hydrochloric acid, sulfuric acid, alkali and tartaric acid solution. For the amphoteric oxide, antimony in the air will burn orderived from the hydrolysis of antimony trichloride.
