Basic Characteristics of Molybdenum Disilicide Powder

Molybdenum disilicide is a gray powder, ceramic powder, chemical formula: MoSi2, molecular weight of 152.11, density 6.3g/cm3, thermal expansion coefficient: 5.1 × 10-6K-1, resistivity of 21 × 10-6Ω. cm, microhardness 1200kg/mm2. A promise material produced molybdenum disilicide ceramic refractory ceramic powder with antioxidant properties and corrosion resistance, and both metal conductivity and high temperature plastic, and also that the lower the proportion of silicon is a binary alloy systems highest volume of an intermediate phase, with the dual properties of metals and ceramics.
