MoSi2=152.12, density 6.26 g/cm3, melting point 2030°C, conductive, at high temperature, a passivation layer of silicon dioxide can be formed on the surface to prevent further oxidation, and its appearance is gray metallic color.
MoSi2 is an intermediate phase with the highest silicon content in the Mo-Si binary alloy system. It has the dual characteristics of metal and ceramics. Therefore, molybdenum disilicide has good high-temperature oxidation resistance, high-temperature plasticity, thermal conductivity and fluidity. It has a wide range of applications in the field of high-temperature structural ceramics.
MoSi2 is mainly used as heating elements, integrated circuits, high-temperature anti-oxidation coatings and high-temperature structural materials. Molybdenum disilicide is used as a structural material for high-temperature parts of aviation, aerospace, and automobile gas turbines.
