Molybdenum disilicide used in high temperature oxidation resistant
coating material , electric heating elements, the integrated electrode
films , structural materials, composite materials, molybdenum
wire reinforcing agents,
wear-resistant materials , structural ceramics and other fields
connecting material
, Distributed in the following industries :
1
) Energy Chemical industry: electric heating element , atomic reactor
unit high temperature heat exchanger , gas burners , high temperature
thermocouple and protection tube , crucible melting vessel ( used for
melting sodium, lithium,
Lead- bismuth, tin and other metals ) .
2
) the microelectronics industry : MoSi2 with some other refractory
metal silicide Ti5Si3, WSi2, TaSi2 and tungsten
sheet so is the LSI gate and
interconnect film important candidate materials .
3 ) aerospace
industry : high temperature oxidation resistant coating material as
widely and deeply studied and applied. Especially as turbine engine
components, such as blades , impellers , the combustor , nozzle , and
Sealing means of the material.
4 ) automotive : automotive turbocharger turbine engine rotor , valve body, spark plugs and engine parts.
Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.
