Abstract: 
The aim of this study was to propose a facile route for the fabrication of TiB2-TiC composite powder by microwave-assisted self-propagating high-temperature synthesis process. For this purpose, TiO2-B2O3-Mg, TiO2-Mg-C and TiO2-B2O3-Mg-C mixtures were heat treated in a domestic microwave oven. The products were characterized by XRD and SEM. Type of reactions in all investigated mixtures was SHS. Result of 2TiO2: B2O3: 9Mg: C mixture showed successful formation of TiB2-TiC-MgO composite. Unwanted MgO compound was leached out by an HCl acid, yielding a pure TiB2-TiC powder. In this work, the possibility of chemical reactions was evaluated by thermodynamic calculations.
