| Abstract: | The submicro W and WC powder can be produced by using of violet tungstic.We used several methods to prepare the specimens,and then studied their morphology by TEM and SEM.It indicates that the shape of W and WC grains is varied,such as dendritic and chain structure,and there are many crystal defects in WC grains. |
