摘要	Hafnium carbonitride (HfCxN1-x) powders were successfully synthesised from a mixture of Hf, C, and HfN powders using the solid-reaction method at 2400 degrees C for 30 min in a nitrogen atmosphere. The basic properties of the as-prepared HfCxN1-x powders, including the particle size, phase composition, microstructure, morphology, chemical bond composition and crystal structure were analysed using X-Ray diffraction, scanning electron mi-croscopy, X-Ray photoelectron spectroscopy, and transmission electron microscopy. The as-prepared HfCxN1-x powders had a singlecrystalline structure of metal carbonitride and simultaneously possessed high purity. The mean particle size of the as-prepared HfCxN1-x powders was approximately 2 mu m, and the chemical composition ratios of Hf, C, and N in the as-prepared powder samples were close to the stoichiometric values. These elements were evenly distributed in the powder samples. The results confirmed that the powders consisted of Hf-C and Hf-N bonds with a Hf/(C + N) ratio of approximately 1. The HfCxN1-x (x = 0.7, 0.6, 0.5, 0.4, 0.3) powders had a cubic crystal structures.
