Final Report, "Thermochemical Studies of Nitrides, Oxynitride, and Oxide Ceramic Materials"

Abstract

Goals• To develop high temperature oxide melt solution calorimetric techniques for a variety of nitrides and oxynitrides• To determine thermodynamics of silicon nitride and of ternary phases in rare earth oxide-silicaalumina -nitrogen systems relevant to silicon nitride processing, thermal barrier coatings, and other applications
