Synthesis of Alumina-Tungsten Carbide Composites by Self-Propagating High Temperature Synthesis Process

Abstract:

Alumina-Tungsten Carbide (Al₂O₃-WC) composites were synthesized by self-propagating high temperature synthesis (SHS) from a powder mixture of WO₃-C-Al. The reaction was carried out in a SHS reactor under static argon gas at a pressure of 0.5 MPa. The standard Gibbs energy minimization method was used to calculate the equilibrium composition of the reacting species. The effects of carbon mole ratio in precursor mixture and diluents of NaCl and Al₂O₃ on the Al₂O₃-WC conversion were investigated using X-ray diffraction and scanning electron microscope technique. The as-synthesized products of Al₂O₃-WC₂-WC powders were concurrently formed and the reduction of W₂C phase was found when added diluents in precursors.
