Synthesis of nanocrystalline zirconium nitride powders by reduction-nitridation of zirconium oxide
Nanocrystalline ZrN powder was synthesized by reduction-nitridation of nanosized ZrO2 powder in ammonia gas with magnesium as the reducing agent. The effects of nitridation temperature, holding time, and Mg:ZrO2 mole ratio on the powder properties were investigated. Cubic phase ZrN powder with a 30-100-nm particle size was synthesized at 1000degreesC for 6 h, under a Mg:ZrO2 mole ratio of 10:1.
