Property:
Antimony trioxide (English name: Antimony trioxide) is a pure white, ultrafine powder with a cubic crystal structure, and it is the most stable compound of antimony. Its molecular weight is 291.5, melting point is 656°C, and its density in the stable cubic form is 5.3 g/cm³. Also known as antimony white, antimony trioxide is an amphoteric oxide—it is insoluble in water, ethanol, dilute sulfuric acid, and dilute nitric acid—but it readily dissolves in concentrated hydrochloric acid, sulfuric acid, strong alkalis, and tartaric acid solutions.
Usage:
⑴ Antimony trioxide is widely used as a synergistic flame retardant in plastic products such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, ABS resin, polyester, polyurethane foam, epoxy resin, and phenolic resin, as well as in synthetic fibers like polypropylene and polyester. When added in specific proportions to flammable polymer materials alongside halogen-based flame retardants, antimony trioxide significantly boosts the material’s oxygen index (OI), enhancing its flame-retardant performance while maintaining excellent cost-effectiveness. It is thus regarded as the most important inorganic synergist for improving the flame-retardant properties of polymers.
⑵ Used as a rubber filler, a passivating agent in the petrochemical industry, a clarifying agent in glass manufacturing, a coloring agent in ceramics and enamel industries, for fabricating optoelectronic components, as a solid lubricant material, in antifouling coatings for ships, and in pharmaceutical applications, among other uses.

It crystallizes in the hexagonal system, has a melting point of 630.5°C, a Mohs hardness of 3, and a density of 6.69 g/cm³. It is a poor conductor of heat and electricity. Antimony is brittle, easily ground into fine powder, but lacks ductility. At room temperature, it does not react with air or oxygen. Additionally, antimony is insoluble in water and generally resists reactions with acids. Applications: ⑴ Antimony is primarily used to enhance the properties of metals and alloys. It finds applications in: - Battery grids, lead plates, and connecting components; - Bearing alloys (such as bearing shells); - Antimony bronze; - Type metal for printing; - Cable armor (sheathing); - Lead sheets, pipes, and foils; - Soldering materials; - Soft tubing made from lead-based alloys via extrusion technology; - Ammunition bullets; - Soldering alloys (particularly for high-quality artistic castings and precision casting); - Hard lead products, among others. ⑵ Antimony compounds—such as antimony trioxide, antimony trisulfide, and various halogenated antimony compounds—are widely utilized across multiple industries, including plastics, synthetic fibers, enamelware, glass manufacturing, paint pigments, ammunition primers, matches, military applications, rubber production, and pharmaceuticals. Manufacturing Facility: Yunnan Muli Antimony Industry Co., Ltd. Packaging: Antimony ingots are packaged in wooden crates, with each crate weighing either 100 kg or 1000 kg net. Custom packaging options are also available upon request. Storage: Store in a dry, clean environment.
