Overview of molybdenum disilicide:
Molybdenum disilicide is a silicon compound of molybdenum, also called molybdenum silicide. Since the radii of the two atoms are not much different and the electronegativity is relatively close,it has properties similar to metals and ceramics.The melting point is as high as 2030 ℃,and it has Conductivity,at high temperatures,a passivation layer of silicon dioxide can be formed on the surface to prevent further oxidation.Its appearance is gray metal color,which is derived from its tetragonal α-type crystal structure,and there are also hexagonal but unstable β-modified crystals.Structure,insoluble in most acids,but soluble in nitric acid and hydrofluoric acid.
Application of molybdenum disilicide:
Molybdenum disilicide is used in high-temperature anti-oxidation coating materials,electric heating elements,integrated electrode films,structural materials,reinforcing agents for composite materials,wear-resistant materials,and connecting materials for structural ceramics.It is distributed in the following industries:
1)Energy and chemical industry:electric heating elements, high-temperature heat exchangers of atomic reactor devices,gas burners,high-temperature thermocouples and their protection tubes,smelting vessels and crucibles(used for smelting sodium,lithium,lead,bismuth,tin and other metals).
2)Microelectronics industry: MoSi2 and some other refractory metal silicides Ti5Si3,WSi2,TaSi2, etc.are important candidate materials for large-scale integrated circuit gate and interconnection film.
3)Aerospace industry: As a high-temperature anti-oxidation coating material,it has been widely and in-depth research and application.Especially as a material for turbine engine components, such as blades,impellers,combustors,nozzles and sealing devices.
4)Automotive industry:turbocharger rotors,valve bodies,spark plugs and engine parts for automobiles.
Molybdenum disilicide can also be used for heating elements of ceramic heaters. Even at a high temperature of 1700°C, Molybdenum silicide will maintain good oxidation resistance by forming a protective film on the surface. Molybdenum silicide is used in aerospace and automotive gas turbines,gas combustion The structure material of the high temperature component of the nozzle and high temperature filter.
