Abstract
A cast oxide ceramic material consisting of Al2O3–Cr2O3 solid solution and ZrO2 inclusions uniformly distributed in it was prepared through metallothermic SHS from highly exothermic thermite-type mixtures containing molybdenum (VI) and chromium (III) oxides and Al/Zr as a combined reducing agent. The influence of green mixture mass on the synthesis parameters, composition, and microstructure of the final products was studied. The optimal conditions for high-temperature synthesis of cast composite oxide material consisting of 80 wt % Al2O3, 10 wt % Cr2O3, and 10 wt % ZrO2 were determined.
期刊介绍：
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
