| Abstract: | Synthesis of W powder by oxide reduction method and fabrication of WC powder by carbonization of W powder are investigated, using violet and blue tungsten oxides as the raw materials, respectively, for the preparation of excellent high grade WC powder. Microstructure and properties of the two raw materials and the obtained W powders and WC powders are studied. The results show that violet tungsten is a suitable raw material for synthesizing uhrafine W powder using the conventional method. The W and WC powders produced from the violet tungsten oxide have better physical properties than those produced from blue tungsten oxide. |
