Chemie und Industrie
Anwendungen
OccurrenceAntimony trisulfide occurs in nature primarily as the mineral, stibnite, which consists of two parallel Sb4S6 chains linked together. It is used in fireworks; in certain types of safety matches; as a pigment in paints; and in the manufacture of ruby glass.
VerwendenAntimony(III) sulfide is used as a red dye in rubber vulcanization. It is used as catalyst, additive, anti- blushing agent, heat stabilizer and used in the production of ruby-colored glass and in plastics as a flame retardant.
Darstellung
synthetischeThe pure sulphide is obtained from its ore. Stibnite is separated from other ores by grinding and flotation. The ore is then heated to 550-600°C in a perforated vessel. The pure molten material is collected and cooled. It is also prepared by passing hydrogen sulfide into a solution of antimony trichloride:2 SbCl3 + 3 H2S → Sb2S3 + 6 HClor treating antimony trichloride solution with sodium thiosulfate.Alternatively, heating antimony metal or antimony trioxide with sulfur forms antimony trisulfide:2 Sb + 3 S → Sb2S32 Sb2O3 + 9 S → 2 Sb2S3 + 3 SO2All these above preparative methods yield amorphous antimony trisulfide.
