| 摘要 |
The present invention relates to a method of producing tungsten carbide by gas phase direct carburization of a tungsten-oxide containing starting material, wherein the starting material is reacted with a reaction gas at an increased temperature. The starting material is first heated to a first temperature greater than or equal to 600° C., before reacting with a reaction gas while increasing the temperature to a second temperature that does not exceed 850° C., wherein the reaction gas is selected from the group consisting of CO and a COH<SUB>2 </SUB>gas mixture comprising up to 20% by volume H<SUB>2</SUB>. |
