| physical and chemical properties | molybdenum trisulfide molecular formula mos3. One of the sulfides formed by molybdenum and sulfur. Brown-black flaky solid or powder, unstable. In vacuum heating is decomposed into MoS2 and S. Almost insoluble in cold water, soluble in hot water, soluble in sodium sulfide or ammonium sulfide solution, the formation of brown red thiomolybdate. Add hydrochloric acid to the ammonium thiomolybdate solution or pass H2S into the slightly acidic molybdate solution to precipitate and obtain mos3. In analytical chemistry, the precipitation reaction was used to determine molybdenum. |
| preparation | first, 37g of sodium sulfide was added to an aqueous solution of sodium molybdate (3g of molybdenum trioxide dissolved in 1.6g of caustic soda) to obtain sodium molybdate sulfide, cooling to 15 ° C, adding ethanol (mass concentration of 95%)60ml, stirring and sulfuric acid (mass concentration of 43%)55ml, the temperature is kept above 15 ° C, the formation of precipitation, filtration, wash until free of sulfate ions. After washing, an additional 20ml of ethanol was added and the mixture was dried in air. Finally, 3.7g of molybdenum trisulfide with a particle size of 1-2 μm was obtained. |
| Application | molybdenum trisulfide can be used as amorphous molybdenum trisulfide cathode material for lithium-sulfur battery; Wear-resistant PA66 composite; inorganic Fullerene molybdenum disulfide; High wear-resistant motor with PTFE sealing gasket. |
