Self-propagating high-temperature synthesis of silicon-nitride ceramic mix using ferro-silicon and ilmenite

The results of an investigation of the high-temperature nitriding of a mixture of ferro-silicon – ilmenite using a complex method of differential-scanning calorimetry are presented. A ceramic mix with the composition Si 3 N 4 – TiN – Si 2 N 2 O – Fe is obtained by the method of self-propagating high-temperature synthesis using as the raw material dust-like ferro-silicon and ilmenite wastes.
