Influence of flux CaO2-Al ratio on the SHS-casting reaction products in WO3-Si-Al system has been investigated in this study. Incorporation of CaO2-Al amounting to 1-5 wt% of total charge has been found to be adequate to form WSi2 intermetallic with a maximum hard-W5Si3 secondary phase. The micro-hardness of tungsten silicides intermetallic product increased significantly with CaO2-Al ratio. The as-SHS-casting products were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM) with energy dispersive x-ray (EDX) technique.
