• Synthesis of New Carbonitride W(C,N) Powder by Heating W+C Mixed Powder in High Pressure Nitrogen Gas.

抄録

The powders of the mono-nitride and mono-carbonitride of W and Mo in VIa group of the periodic table of elements have not been commercialized. The main reason seems to be in the fact that the nitrides of W and Mo can not be synthesized by heating those metals in nitrogen gas of normal pressure. We tried to synthesize WN and W(C, N) by heating W powder and W+C mixed powder respectively in nitrogen gas of high pressure up to 190 MPa, and found that the powder of tungsten carbonitride, i.e., W(C, N) with nitrogen content up to about 20 at% could be synthesized, while WN could not.
