We have already succeeded in synthesizing new mono-carbonitrides W (C, N) and Mo(C, N) with 11-20at%N and 14-25at%N respectively by heating W+C and Mo+C mixed powder in high-pressure N₂ gas of 10-160MPa at 1523-1673K. In this study, the synthesis of new (W, Mo)(C, N) powder was tried by heating W+Mo+C mixed elemental powder and W-Mo solid solution alloy+C mixed powder in such high-pressure-N₂gas. (W, Mo)(C, N) with N content of 14-24at% could be synthesized at 25 -160MPa in case of (W-Mo)+C mixed powder (Metal/C atomic ratio is 1/1), while (W, Mo)(C, N) could not in case of W+Mo+C mixed elemental powder.
