1.Performance and use

Antimony sulfide is commonly known as raw antimony. Very pure antimony trisulfide. It is a dark gray needle shaped crystal. Generally, high-grade antimony ore is melted and refined by heating it to 650 ℃ in a crucible furnace or a reverberatory furnace. Antimony sulfide can be sold directly as a commodity. The binary compounds of sulfur and antimony include antimony trisulfide Sb2S3 and antimony pentasulfide Sb2S5. Pure antimony trisulfide is an orange solid or black gray crystalline or powder with metallic luster, with a relative density of 4.12, a melting point of 550 ℃, and a boiling point of approximately 1150 ℃. Insoluble in water, amphoteric, soluble in concentrated hydrochloric acid, sodium hydroxide solution, and sulfide

Mainly used in the production of safety matches, firecrackers, military weapons, and as a hardener or pigment in the rubber industry

Mainly used for manufacturing matches and fireworks, various antimony salts, and colored glass. Rubber industry used as vulcanizing agent and military industry, etc

Antimony trisulfide is the most practical antimony compound in industry, which can be used as a rubber vulcanizing agent. Manufacturing of fireworks, glass, explosives, paint and pigments.
