Product Description
Antimony trioxide is an inorganic compound with the chemical formula Sb2O3. The natural product is called antimony hua, commonly known as antimony white, which is white crystalline powder with a melting point of 655°C and a boiling point of 1550°C, soluble in concentrated hydrochloric acid, sulfuric acid, alkali solution and hot tartaric acid solution, slightly soluble in water, dilute nitric acid and dilute sulfuric acid

Product usage
Used as a pigment, flame retardant, mordant, catalyst, and also used in the synthesis of antimony salts: 1. Used as a flame retardant for various resins, synthetic rubber, canvas, paper, paint, etc., and a catalyst for petrochemical and synthetic fibers. It is used in the manufacture of mordants and opacifiers, and is the raw material for the synthesis of antimony salts. Used in the enamel industry as an additive to increase the opacity and surface gloss of enamel. The glass industry is used as a decolorizing agent instead of arsenous acid. Medicine, metallurgy, military industry, etc.
2. Antimony trioxide is an additive flame retardant, which is often used together with other flame retardants and smoke suppressants, and synergistic effects can be produced between the components. At the initial stage of combustion, antimony trioxide is first melted, forming a protective film on the surface of the material to isolate the air, and reducing the combustion temperature through internal endothermic reactions. Antimony trioxide is gasified at high temperature, which dilutes the oxygen concentration in the air, thereby playing a flame retardant role.
3. Commonly used polycondensation catalysts are used in the polycondensation of ethylene terephthalate at about 0.03%. It is also used as a flame retardant for various resins, synthetic rubber canvas, paper, paint, etc. Antimony trioxide is also a good covering agent, used as a white paint pigment. It is used in the manufacture of mordants and opacifiers, and is also the raw material for the synthesis of antimony salts. It can be used as a decolorizer instead of arsenous acid in the glass industry.
4. Used in fireproof coatings, pigments, enamel and glass industries and in the preparation of antimony potassium tartrate. Also used as a mordant.
5. Antimony trioxide is the earliest flame retardant used, suitable for epoxy resin, polyurethane, polystyrene, polyvinyl chloride, polyester, etc. When used alone, the flame retardant effect is low, and when used in combination with halogen compounds, it has a good synergistic effect, and the flame retardant effect is significantly improved. It is also used in the manufacture of enamel glazes, pigments, drugs, mordants, etc.
