China Direct Factory: Sodium antimonate (Nasb (OH) 6)
Sodium antimonate is a white powder with granular and equiaxed crystals. Soluble in tartaric acid, sodium sulfide solution, concentrated sulfuric acid, slightly soluble in alcohols and ammonium salts, insoluble in acetic acid, dilute alkali, and dilute inorganic acids. Insoluble in cold water, hydrolysis occurs in hot water to form colloids.
Sodium pyroantimonate is an inorganic salt compound of antimony with low toxicity.
It is produced from antimony products such as antimony oxide through alkali.
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 flame retardant wires. Also used as flame 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 depolymerization during the operation of antimony oxide flame retardants commonly used in sensitive polymerization.
