Antimony trioxide is an inorganic compound with the chemical formula Sb2O3. Natural products called antimony, commonly known as antimony white, white crystalline powder. Melting point 655 ℃. Boiling point 1550 ℃. Soluble in sodium hydroxide solution, hot tartaric acid solution, bitartrate solution and sodium sulfide solution, slightly soluble in water 370±37 μg/L, dilute nitric acid and dilute sulfuric acid. There is a carcinogenic possibility. There are two kinds of preparation methods, dry and wet, which are mainly used for white pigments, paints and plastics, and can play the role of pigments and flame retardants.

The main use of antimony trioxide:

Use one: Antimony trioxide used as white pigment, white glass, enamel, medicine, cement, filler, mordant and fire retardant coating, etc;

Use 2: Antimony trioxide is widely used as a flame retardant in plastics, rubber, textile, chemical fiber, pigment, paint, electronics and other industries, and is also used as a catalyst and production raw material in the chemical industry;

Use three: antimony trioxide used as high purity reagent, mordant and anti-light agent, also used for pigment and potassium antimony tartrate preparation;

Use four: Antimony trioxide is used as a flame retardant for various resins, synthetic rubber, canvas, paper, coatings, etc., and as a catalyst for petrochemical and synthetic fibers. Used in the manufacture of mordant, milky white agent, is the synthesis of antimony salt raw materials. It is used industrially as an additive to increase the opacity and surface luster of enamel. The glass industry is used as a decolorizing agent instead of arsenous acid. Medicine, metallurgy, military industry, etc.

Use five: excellent inorganic white pigment, mainly used for paint coloring. Flame retardant for various resins, synthetic rubber, canvas, paper, paint, petrochemical, synthetic fiber catalyst. Used in the manufacture of mordant, milky white agent, is the synthesis of antimony salt raw materials. It is used industrially to increase the opacity and surface luster of enamel. The glass industry is used as a decolorizing agent instead of sub.

Antimony trioxide (also referred to as antimony oxide, commonly known as antimony white) molecular formula: Sb2O3 molecular weight: 291.5 Antimony trioxide is one of the inorganic flame retardants that have been used for a long time. It is mainly used as a flame retardant synergist to cooperate with halogen-containing compounds. It plays a flame retardant role in their thermal decomposition process and can replace some halogen compounds. It can be applied to plastics, rubber, chemical fiber, enamel, pigment, paint, glass, glass, electronics and other industries.

3.5 zinc borate water molecular formula: 2ZnO • 3B2O3 • 3.5H2O molecular weight: 434.51. Zinc borate is an inorganic additive flame retardant, which is characterized by good thermal stability, I .e. flame retardant and smoke elimination. It can replace antimony trioxide in some products and can also be used in conjunction with other inorganic flame retardants with better effect. Anhydrous zinc borate molecular structure formula is 2ZnO · 3B2O3, white powder, excellent fluidity, temperature resistance to 600 ℃, low heat release rate. Very low water solubility, no migration, and excellent charring performance, can be compounded with other additives into halogen-free expansion flame retardant, can be used as a high processing temperature polymer (polyether ketone, polyalum, polyester, nylon, fluorine-containing polymer, etc.) excellent flame retardant and smoke suppression agent.
