Antimony(III) oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite.[2] Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions with hydrolysis.

White powder, insoluble in water, soluble in acid and sodium hydroxide solution. For the white pigments, paints and plastics, from pigments and flame retardant effect. The main purpose 1. For a variety of resins, synthetic rubber, canvas, paper, paint and other flame retardants, petrochemicals, synthetic catalysts. For the manufacture of mordant, white agent, antimony salt is synthesized. Enamel industry as additives to increase the opacity of enamel and surface gloss. Glass industry as a bleaching agent instead of arsenious acid. Pharmaceutical, metallurgical, military and other. 2. antimony trioxide flame retardant additive belonging, often with other flame retardants, smoke suppressants and use, between the component may produce a synergistic effect. Antimony trioxide in the early stages of combustion, first molten material isolated from the air surface protective film is formed by an internal endothermic reaction, reducing the combustion temperature. Antimony trioxide is gasified at a high temperature, dilute the concentration of oxygen in the air, and thus play a flame retardant.

Melting point 655 C Boiling point 1425 C. Sublimate when heated to 400 C in high vacuum. vapor pressure: 13.3 hPa (660 C) storage temp: Store below +30 C. Appearance : white superfine powder the crystal structure is mainly cubic crystal Application: 1). Used as white pigment, white glass, enamel, medicine, cement, filler, mordant and fire retardant coating, etc 2). As a flame retardant widely used in plastics, rubber, textile, chemical fiber, pigment, paint, electronics and other industries, but also as a catalyst and production raw materials in the chemical industry 3). As a high purity reagent, mordant and anti light agent, also used in the preparation of pigments and antimony potassium tartrate 4). Used as flame retardant for various resins, synthetic rubber, canvas, paper, paint, etc., 5). A fine inorganic white pigment, mainly used for coloring paints. Used as flame retardant for various resins, synthetic rubber, canvas, paper, paint, etc. 6). Antimony trioxide is a good masking agent and is used as a white paint pigment.

Antimony Oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions with hydrolysis. A mixed arsenic-antimony oxide occurs in the nature as the very rare mineral stibioclaudetite

Dust-free antimony trioxide is made from fine Sb2O3 powder treated by special techniques to moisturize it slightly thus avoiding damages to human body that may be caused by dusts in the application of the product while achieving high fire-retarding efficiency and plasticization. It is easier to combine with base materials and even dispersing. This product is applied mainly as retardant additive and plasticization for polyvinyl chloride, synthetic fiber, synthetic rubber and vinyl resin, etc. Upon customerâ??s request, we can adopt diversified ingredients of organic solvents such as mineral oil, Chlorinated Paraffin, glycol, DOP, DIDP, etc.
