Self-Propagating High-Temperature Synthesis of Composite Material Based on Stabilized Zirconium Oxide1

Abstract

Ceramic composite materials based on stabilized zirconium oxide with up to 9 mol.% of the stabilizing additive Y₂O₃ were obtained in this work by self-propagating high-temperature synthesis. The effect of the stabilizing additive content on the combustion characteristics of the obtained materials and their phase composition was studied. Introduction of Y₂O₃ into the studied materials was shown to lead to the formation of the cubic modification of ZrO₂ in the synthesis products, while three ZrO₂ modifications were observed without introduction of Y₂O₃ into the synthesis products.
