Molybdenum disilicide (MoSi2)

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.
