Molybdenum disilicide (MoSi2) is a very common application of heating element materials with high temperature oxidation resistance, excellent corrosion resistance and high melting point and other characteristics. Its oxidation resistance is due to heating of the gas-tight glass surface film, so that from oxygen, nitrogen, carbon monoxide and sulfur dioxide damage, in the 1700-2000 o K temperature molybdenum disilicide heating can work two, three years . But poor mechanical properties of molybdenum silicide applications, if the addition of SiC in the molybdenum silicide to form a composite material, this material will diffuse into the SiC matrix of molybdenum disilicide, the formation of molybdenum atoms and silicon atoms with two-metal compounds , its high temperature strength of molybdenum disilicide monomer than 8 times higher, so prospects are so popular.
