Method of producing ternary lead molybdenum sulfides

摘要

The method of preparing Pb.sub.x Mo.sub.y S.sub.z where x = 0. 8-1.1, y = 4.5-5.6, and z = 5.4-7.2 comprising the steps of mixing commercial reagent grade powders of the reactants, heating in a sealed, evacuated reaction vessel to a temperature of 950-1150 C, maintaining the temperature until the compound is formed, and then cooling the compound at a controlled rate not in excess of 4 C per minute.
