Abstract

The synthesis of new mono-carbonitride powders of W and Mo, i.e., W(C, N) and Mo(C, N), have already been succeeded by authors by a normal-pressure method, i.e., heating metal powder in CH₄+NH₃ mixed gas of normal-pressure. In this study, the synthesis of mono-carbonitride of Cr in the same VIA group in the periodic table as W and Mo was attempted by the normal-pressure method. As the result, Cr(C, N) containing a small amount of Cr₃C₂ and Cr₂N was obtained by heating of 1173 K-57.6ks. The nitrogen content (N/Cr)of Cr(C, N) in the product was estimated to be between about 40 and 60 at%. This value was considerably lower than 78-92 at% of pure Cr(C, N) synthesized by high-pressure method, i.e., heating metal+C mixed powder in N₂ of 100-150MPa.
