Nanocrystalline CrN powder was synthesized by the direct nitridation of nanosized Cr 2 O 3 powder. Powder X‐ray diffractometry patterns indicated that pure cubic‐phase CrN powder could be obtained by nitridation at 800°C for 8 h. Transmission electron microscopy images showed that the particle sizes were 40–80 nm. The effect of the nitridation temperature and holding time on the powder properties was studied.
