| Abstract: | Molybdenum disilicide was synthesized successfully from element Mo and Si powders using self -propagating high - temperature synthesis technology. The effect of the particle size of reactants, the relative density of compact, the preheating temperature, the content of diluent and the reaction atmosphere on the SHS process of MoSi2 was discussed based on the experimental results. The phase constituent and the morphology of the final product were inspected by X - ray diffraction ( XRD) and scanning electron microscopy ( SEM) , respectively. |
