Abstract

Nitride and carbide powders by a carbothermal reduction route and, if appropriate, nitration of metal oxides capable of being employed especially for the manufacture of ceramics and having a specific surface of between 30 and 250 m<2>/g. Process for the manufacture of powders comprising the following stages: a) from metal oxide or oxides with a particle size of less than 10 mu m, a binder generating carbon, not later than during the carbothermal reduction reaction and, if appropriate, additional carbon, manufacture of granules with a controlled pore volume, b) carbothermal reduction reaction of the granules obtained under a, if appropriate in the presence of an atmosphere containing nitrogen, c) decarbonisation, d) obtaining powders. s
