METHOD OF PRODUCING METAL SULFIDES

摘要

PURPOSE: A method of producing metal sulfides directly from metal and sulfur by mechanothermal operation is provided to reduce waste byproduct generation as well as improve process efficiency. CONSTITUTION: The production method of metal sulfides includes the steps of charging a sealed jar with sulfur to be alloyed, at least one particulate/granular metal species, together with steel balls; rotating the sealed jar for preparing a mutually diffused compound or a chemically connected metal sulfide through a series of crush-conjunction-crush process in the sealed jar; and chemically stabilizing above mutually diffused compound or chemically connected metal sulfide by heater mounted on the surface of the sealed jar.
