Abstract
Intermetallic tungsten silicide alloy WSi2–W5Si3 was successfully synthesized via magnesiothermic SHS reaction in the WO3–Si–Mg system. Equilibrium composition of combustion products was calculated by standard Gibbs energy minimization method and the combustion products were characterized by XRD, SEM, and EDX. The synthesized alloy had a density of 8.97 g/cm3 (96.4% of theoretical). The process can be readily recommended for practical implementation.
