PREPARATION METHOD OF METAL SULFIDE

摘要

PURPOSE: A preparation method of high purity metal sulfide by mechanical alloying method which is characterized by repeating grinding-bonding- grinding process is provided to yield fine metal sulfide or composite metal sulfide powders without by-products. CONSTITUTION: The metallic sulfide is prepared by rotating an attriter jar or a rotator in jar filled with sulfur(S) and at least one metal component(pure metal or metal alloy) in a type of powders or granules, and rigid balls.
