Self-propagating high-temperature synthesis of Al2O3/TiC-based ceramic materials

  • Published:
Inorganic Materials Aims and scope

Abstract

Dense Al2O3/TiC composite ceramic materials are synthesized using the SHS compaction of mixtures based on TiO2 + Al + C. Mineralizing and heating additives are introduced into compounds. The phase composition and microstructure of combustion products are investigated by x-ray phase analysis, electron microscopy, and microprobe techniques. Two Al2O3 modifications are revealed. Special attention is devoted to the presence of residual graphite. The mechanisms of phase formation and formation of the microstructure of combustion products are considered.
