Physical and chemical properties: Antimony trioxide is an inorganic compound. White crystalline powder. It turns yellow when heated, and turns white when cooled. Odorless. The melting point is 655°C. The boiling point is 1550°C. It can sublimate when heated to 400°C in high vacuum. Soluble 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.

The main purpose:

1. Used as white pigment, white glass, enamel, medicine, cement, filler, mordant and fireproof coating, etc.

2. As a flame retardant, it is widely used in plastics, rubber, textiles, chemical fibers, pigments, paints, electronics and other industries, and is also used as a catalyst and raw material in the chemical industry

3. It is used as high-purity reagent, mordant and anti-light agent, and also used in the preparation of pigments and antimony potassium tartrate.

4. Used as a flame retardant for various resins, synthetic rubber, canvas, paper, paint, etc., as 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.

5. Excellent inorganic white pigment, mainly used for coloring of paint. Used as a flame retardant for various resins, synthetic rubber, canvas, paper, coatings, etc., as a catalyst for petrochemicals and synthetic fibers. It is used in the manufacture of mordants and opacifiers, and is the raw material for the synthesis of antimony salts. The enamel industry is used to increase the opacity and surface gloss of enamel. The glass industry is used as a decolorizing agent instead of arsenous acid.

6. Antimony trioxide is a good covering agent, used as a white paint pigment. Used as a flame retardant for various resins, synthetic rubber canvas, paper, paint, etc., as a catalyst for petrochemicals and synthetic fibers. It is used in the manufacture of mordants and opacifiers, used in the manufacture of white glass, enamel, tartar, medicine, cement, and is also a raw material for the synthesis of antimony salts, an additive in the enamel industry, to increase the opacity and surface gloss of enamel. In the glass industry, it is used as a decolorizing agent instead of arsenous acid.
