Antimony Trioxide Sb2o3 Diantimony Trioxide 1309-64-4 Sb2O3 FOR FLAME RETARDANT
Identification
Antimony trioxide (chemical formula: Sb2O3) is an inorganic compound. The natural product is called Dihua, commonly known as Sb white, white crystalline powder. The temperature of 655 ° C. The boiling point is 1550 °C. Dissolved in sodium hydroxide solution, hot tartaric acid solution, hydrogen tartrate solution and sodium sulfide solution, slightly soluble in water 370±37 μg/L, dilute nitric acid and dilute sulfuric acid. There is a possibility of carcinogenesis. The preparation method is dry and wet, mainly used for white pigments, paints and plastics, and can play the role of pigment and flame retardant.
White crystalline powder. It turns yellow when heated and turns white after cold. Odorless. The temperature of 655 ° C. The boiling point is 1550 °C. Sublimation by heating to 400 ° C under high vacuum. Dissolved in sodium hydroxide solution, hot tartaric acid solution, hydrogen tartrate solution and sodium sulfide solution, slightly soluble in water 370 ± 37 μg / L, dilute nitric acid and dilute sulfuric acid.

Application
Use one: used as white pigment, white glass, enamel, medicine, cement, filler, mordant and fire retardant coating, etc.
Use 2: As a flame retardant, it is widely used in plastics, rubber, textile, chemical fiber, pigment, paint, electronics and other industries. It is also used as a catalyst and raw material for the chemical industry.
Use 3: used as high purity reagent, mordant and lightproofing agent, also used in the preparation of pigment and bismuth potassium tartrate
Use 4: Used as a flame retardant for various resins, synthetic rubber, canvas, paper, paint, etc., a catalyst for petrochemicals and synthetic fibers. It is used to manufacture mordant and opacifier, and is a raw material for synthesizing strontium salt. The enamel industry is used as an additive to increase the opacity and surface gloss of the enamel. The glass industry is used as a decolorizing agent in place of arsenious acid. Medicine, metallurgy, military and so on.
