Abstract

The method of self-propagating high-temperature synthesis (SHS) is applied to prepare cast oxynitride ceramics using a Fe2O3 + 4Al thermite mixture. The nitrogen-containing components of the mixture were AlN and Si3N4 additives. The synthesis was performed in a reactor at an initial nitrogen pressure of 8MPa. The nitrogen-containing additives are demonstrated to influence the burning rate and combustion limits of the mixtures, as well as the yield and chemical composition of the cast ceramics.
