METHOD FOR PRODUCING TUNGSTEN CARBIDE

摘要

A method of producing tungsten carbide by gas phase direct carburization of a powdery, tungsten-oxide containing starting material, wherein the starting material i s reacted with a reaction gas at an increased temperature, characterized in that the tungsten - oxide containing starting material is heated to at least 600.degree.C and is then reacted wit h the reaction gas while increasing the temperature to a maximum temperature of up to 850.degree.C, wherein a reaction gas is used which consists of CO or is a CO/H2 gas mixture that contains up to 2 0% by volume of H2 (Fig. 1).
