Hafnium carbide powder was synthesized by sol-gel polycondensation of hafnium chloride with citric acid. The starting materials were dissolved in water and mixed on a hot plate until a precomposite gel was formed. Pyrolysis of these gels resulted in monoclinic hafnia and cubic hafnium carbide materials, which after subsequent heat treatment completely transformed into hafnium carbide. The obtained materials were analyzed by means of X-ray diffraction and electron microscopy investigations. The results showed that the obtained carbide powder was composed of nearly equiaxed particles of narrow size distribution. Characterization by nitrogen adsorption showed that the precomposite gels and the composite powders were micro and mesoporous materials with high surface areas.
