Sulfide powder refers to the chemical compounds powder with large families of inorganic and organic compounds, e.g. copper sulfide, Zinc sulfide, molybdenum disulfide, tungsten disulfide powders and so on.
Zinc sulfide, is also named zinc sulphide, which is with chemical formula ZnS. The molecular weight of zinc sulfide is 97.445, CAS no. 1314-98-3. Zinc sulfide powder is not soluble in water, ZnS melting point 1700℃, the density of ZnS powder is 4.09 g/cm3.
Molybdenum disulfide, is also named molybdenum disulphide, which is with chemical formula MoS2. The molecular weight of molybdenum disulfide is 160.07, CAS no. 1317-33-5. Molybdenum disulfide powder is not soluble in water, MoS2 melting point 2375℃, the density of MoS2 powder is 4.80 g/cm3.
Tungsten disulfide, is also named tungsten disulphide, which is with chemical formula WS2. The molecular weight of tungsten disulfide is 247.97, CAS no. 12138-09-9. Tungsten disulfide powder is not soluble in water, WS2 melting point 1250℃, the density of MoS2 powder is 7.5 g/cm3.
Sulfides and their similar compounds include a series of metals and semi-metallic elements combined with S, Se, Te, As, Sb, Bi minerals.
Sulfide powders are widely used in industrial field. Molybdenum disulfide is a catalyst in organic synthesis. Since sulfur-containing organic compounds such as thiophene poison the common hydrogenation catalyst, molybdenum disulfide can be used to catalyze the hydrogenation reaction of sulfur-containing organic substances. Cadmium sulfide can be used to make photo-voltaic cells. Lead sulfide is used to make infrared sensors.
Zinc sulfide and cadmium sulfide are used to make phosphors, and high purity cadmium sulfide is a good semiconductor. Tetraphosphorus trisulfide is used to make matches and fireworks. Tetraphosphorus tetrasulfide is used in the manufacture of insecticides, lubricating oil additives and flotation agents. Sodium sulfide is widely used in the manufacture of sulphur dyes, production of organic drugs and pulp, etc. Calcium sulphide and strontium sulfide are used to make luminescent lacquers.
