Summary

Zirconium carbide (ZrC) powders were produced by the carbothermal reduction reaction of zirconia and carbon. Solution-based processing was used to achieve a fine-scale mixing of the reactants. The reaction was substantially completed at relatively low temperature (1400°C) and the resulting ZrC product had small average crystallite size (∼120 inn). ZrC powder compacts were pressureless sintered to >90% relative density at 1800°C.
