Sodium pyroantimonate

1. Description 

Sodium antimonate is a white solid that is soluble in water. It has strong oxidizing and corrosive properties. It decomposes at high temperatures.

Sodium antimonate is an inorganic salt compound of antimony with low toxicity. It is synthesized by oxidation of antimony products such as antimony oxide, and appears as a white powder or grayish white powder. There are two types: granular crystals and equiaxed crystals. The melting point is 1200 ºC and the boiling point is 1400 C. Soluble in tartaric acid,sodium sulfide solution, concen-trated sulfuric acid, slightly soluble in alcohol and ammonium salts, insoluble in acetic acid, dilute alkali, and dilute inorganic acids, insoluble in cold water, with good chemical stability.

3. Application 

Sodium antimonate is mainly used as a clarifying agent and defoamer for photovoltaic solar glass, black and white, and color display screen cathode ray tube glass. Clarifying and defoaming agents for high-end glass such as fiberglass, gemstone glass, and high-end glass tableware, as well as flame retardants widely used in engineering thermoplastic plastics and rubber, such as flame retardant electronic equipment casings, flame retardant carriages, and flameretardant wires. Also used asFlame retardants for textiles, plastics, building materials, etc. Widely used internationally as a flame retardant to replace antimony oxide, it has been proven through scientific experiments and production that it has superior technical performance. Used in all polymers, it has better flame retardancy and lower light blocking and coloring strength in saturated polyester and engineering thermoplastic. It has the characteristic of low reactivity, which is prone to depolymerizasensitive polymerization. tion during the operation of antimony oxide flame retardants commonly used in sensitive polymerization.
