Uses and synthesis of Diantimony trioxide powder

Diantimony trioxide powder is white crystalline powder, yellow after heating, white after cooling, odorless; Melting point 655℃, boiling point 1425℃. Sublimation when heated to 400℃ in high vacuum. Soluble in sodium hydroxide solution, hot tartric acid solution, bitartrate solution and sodium sulfide solution, slightly soluble in water, dilute nitric acid and dilute sulfuric acid. The relative density is 5.67. Diantimony trioxide is the earliest applied flame retardant, often used with other flame retardants, smoke suppressants, each component can produce synergistic effect.

Applications/Functions of Diantimony trioxide powder

1. Diantimony trioxide powder is used as a high purity reagent, mordant and anti-light agent, as well as in the preparation of pigments and antimony potassium tartrate
2. Diantimony trioxideas a flame retardant is widely used in plastics, rubber, textile, chemical fiber, pigment, paint, electronics and other industries, and is also used as a catalyst and raw material in the chemical industry
3. Excellent inorganic white pigment, mainly used for coloring paint. Used in various resins, synthetic rubber, canvas, paper, coatings and other flame retardants, petrochemical, synthetic fiber catalyst. Diantimony trioxide powder Used in the manufacture of mordant, opalescent agent, is the synthesis of antimony salt raw materials. The enamel industry is used to increase the opacity and surface gloss of enamel. Used in glass industry as a decolorizing agent instead of arsenite.

Production methodprocess of Diantimony trioxide powder

The antimony trioxide vapor generated by oxidation is collected, and after condensation, soda ash is used as a flux, and coke is heated and reduced to produce antimony metal. The resulting metal Antimony is then oxidized in air to obtain Diantimony trioxide powder.
