EINECS: | 239-444-7 | Molecular Weight: | 192.73 |
---|---|---|---|
Molecular Formula: | NaSbO3 | Alias: | Sodium Antimonate |
CAS No: | 15432-85-6 | Appearance: | White Powder |
High Light: | sodium antimonate,strontium carbonate |
Uses: Sodium antimonate used as a clarifying agent in kinescope, optical glass and a variety of advanced glass, flame retardants in textiles and plastic products; as a filler in the enamel opaque milky agent, manufacture castings with paint; and as Antacid ingredient in paint tin, steel production ; chemical analysis for the identification of sodium ions. Crushed by a block of antimony mixed with sodium nitrate heated air through the reaction, and then the nitric acid leach derived. Crude antimony trioxide can also be mixed with hydrochloric acid, and then the chlorine chlorination, hydrolysis, with an excess of soda and derived.
