Abstract
Molybdenum(VI) oxide reacted with hydrogen sulphide to give, either a mixture of molybdenum(IV) sulphide and molybdenum(IV) oxide, which is very difficult to separate, or, at higher temperatures molybdenum(IV) oxide only. In the presence of ammonium chloride, the reaction gave pure lubricant grade molybdenum(IV) sulphide. The reaction was studied with different process variables. Under optimum can be conditions 81.5% pure MoS~2~ was obtained at 700°C. The overall reaction represented as:
The densities of the products were measured. X‐ray diffraction patterns of pure samples were taken.
