(1) Antimony is mainly used for improving performance of metal or alloy. It is applied to grids of storage batteries, lead plates and joint fittings; bearing alloy (bearing bush); antimony bronze; type metal; cable armoring (wrapping); lead plates, lead pipes and lead foil; solder; lead-based alloy hoses made by impact extrusion technology; projectiles; soldering tin (used in high-quality artistic casting works and precision casting); hard lead, etc.
(2) It is used for manufacturing antimony trioxide, antimony trisulphide, antimony halides, etc. Antimony compound is widely used in plastic, chemical fiber, enamel, glass, paint pigments, primer ingredients of bullets and cannonballs, matches, military industry, rubber, medicine, and other industries.
(1) Antimony trioxide is applied to plastic products such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, ABS resin, polyester, polyurethane foamed plastic, epoxy resin and phenolic resin, as well as synthetic fiber like polypropylene and polyester as flame retardant synergist in a large amount. Adding halogen flame retardant and antimony trioxide synergist in a certain ratio in high polymer materials may obviously improve OI of material burning. With a remarkable strong flame retardant effect and high cost performance, it is the most important flame retardant synergist.
(2) It is used as rubber filler, passivator of petrochemical industry, clarifier of glass manufacturing, colorant of ceramics and enamel industry, and used in manufacturing of photoelectric elements, solid lubricating materials, anti-fouling paint of vessels, medicine, etc.
