A description is given of a process for manufacturing nitrides for ceramic materials, in particular AlN, in which the element to be converted to the nitride is anodically oxidised. This oxidation is carried out in the presence of a nitrogen compound which can be reduced under the electrolysis conditions and of a substance which increases the conductivity. The electrolysis is optionally followed by...
