摘要:
The invention concerns a method for preparing ceramic powders in the presence of a carbon powder comprising a step which consists in homogenizing a mixture of particles capable of resulting in a ceramic by heat treatment. Said method can be carried out in the presence of an accelerated solvent and provides, at reduced energy consumption, carbon-coated ceramic powders and then ceramics.
