The development history of molybdenum disilicide MoSi2
Molybdenum silicide was discovered in 1906. Under different conditions, silicon and molybdenum can form molybdenum silicide (Mo3Si), pentamolybdenum trisilicide (Mo5Si3) and molybdenum disilicide (MoSi2).
The most important of the three molybdenum silicides is molybdenum disilicide (MoSi2), which is a Dalton-type intermetallic compound. The combination of atoms in its crystal structure presents the coexistence of metal bonds and covalent bonds, and has excellent high-temperature essential characteristics. .
As early as 1907, molybdenum disilicide was used as a high-temperature anticorrosive coating material for metals, and molybdenum disilicide heating elements appeared in the 1950s.
Molybdenum disilicide as a structural material was first proposed in the early 1950s, but it was not taken seriously until the 1970s with the emergence of the concept of brittle materials as structural materials. In the 1980s, rapid progress took place, and its research work was widely carried out all over the world.
Molybdenum disilicide MoSi2 powder overview
Molybdenum disilicide is an inorganic compound with the chemical formula MoSi2, which is a gray metallic solid. Insoluble in most acids, but soluble in nitric acid and hydrofluoric acid. The radii of the two kinds of atoms are not much different, the electronegativity is relatively close, and they have properties similar to those of metals and ceramics. Molybdenum disilicide is conductive and can form a passivation layer of silicon dioxide on the surface at high temperatures to prevent further oxidation. It 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.
Molybdenum disilicide MoSi2 powder application
Molybdenum disilicide MoSi2 is used in high-temperature oxidation-resistant coating materials, electric heating elements, integrated electrode membranes, structural materials, composite reinforcement materials, wear-resistant materials, structural ceramic connecting materials and other fields, and are distributed in the following industries:
1) Energy and chemical industry: MoSi2 is used as electric heating element, high temperature heat exchanger of atomic reactor device, gas burner, high temperature thermocouple and its protection tube, smelting vessel crucible (used for smelting sodium, lithium, lead, bismuth, tin and other metals) .
2) Microelectronics industry: MoSi2 and other refractory metal silicides Ti5Si3, WSi2, TaSi2, etc. are important candidates for large-scale integrated circuit gates and interconnections.
3) Aerospace industry: MoSi2 as a high-temperature anti-oxidation coating material, especially as a material for turbine engine components, such as blades, impellers, combustion chambers, nozzles and sealing devices, has been widely and in-depth Research and application.
4) Automobile industry: Molybdenum disilicide MoSi2 is used in automobile turbocharger rotors, valve bodies, spark plugs and engine parts.
