Abstract

Titanium nitride and silicon nitride nanopowders are subjected to microwave treatment to stimulate reduction and nitration reactions. It is established that oxygen content of the nanopowders after microwave treatment is 30-60% lower than that of the starting powders. The completeness of thermochemical treatment and the particle size distribution depending on the amount of phases that absorb microwave energy are studied.
