Summary
Hafnium carbide (HfC) powders were produced by the carbothermal reduction reaction of hafnium dioxide and carbon. Fine-scale mixing of the reactants was achieved by using solution processing to synthesize a single-source Hf-O-C precursor. HfC powders with small average crystallite size (-50 nm) were produced at 1475°C, although higher temperature was required to complete the carbothermal reduction reaction.
