Application areas
Antimony ingot:
⑴ Primarily used to enhance the properties of metals or alloys. Applications include: battery grid plates, lead sheets and connector components; bearing alloys (bushings); antimony bronze; type metal; cable armor (sheathing); lead sheets, lead pipes, and lead foils; solder materials; soft tubing made from lead-based alloys via extrusion technology; bullets; and high-quality soldering alloys used in fine art casting and precision molding, as well as hard lead products.
(2) Used in the production of antimony trioxide, antimony trisulfide, and antimony halides, among others; its antimony compounds find extensive applications across various industries, including plastics, synthetic fibers, enamel, glass, paint pigments, primers for firearm and artillery propellants, matches, military manufacturing, rubber, and pharmaceuticals.
Antimony trioxide:
⑴ 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. By incorporating halogen-based flame retardants along with antimony trioxide synergists into flammable polymer materials at specific ratios, the oxygen index (OI) of the material can be significantly improved, leading to markedly enhanced flame-retardant performance. This combination offers excellent cost-effectiveness and is considered the most important inorganic flame-retardant synergist.
(2) 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.
