Global MoSi2 Powder market trend 2025-2026 High Purity Molybdenum Silicide MoSi2 Powder CAS 12136-78-6, 99.5% by Newsfluffylogic

Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of MoSi2 Powder.

 About Molybdenum Silicide MoSi2 Powder: 
MoSi2 is an intermetallic compound, molybdenum silicide is a refractory ceramic, mainly used for heating elements. It has a medium-density, a melting point of 2030 ° C, which is electrically conductive. At high temperatures, it forms a passivation layer of silica to protect it from further oxidation. The thermal stability of MoSi2 and the thermal stability of its high radiation make such materials and high radiation coatings in thermal shields from the atmosphere as they are used next to WSI2. MoSi2 is a material with a four-square crystal structure (α-modified) gray metal; its β-modification is hexagonal and unstable. It is insoluble in most acids but is dissolved in nitric acid and hydrofluoric acid.
 
Although MoSi2 has excellent oxidation and high Young's modulus at temperatures above 1000 ° C, it is brittle at lower temperatures. Moreover, at 1200 ° C or more, it will lose creep resistance. These properties are limited to their structural materials but can be shifted by using it as a composite with another material. 

Molybdenum disilicide (MoSi2) is a promising candidate material for high-temperature structural applications. It is a high melting point (2030 C) material with excellent oxidation resistance and a moderate density (6.24 g/cm3). However, low toughness at low temperatures and high creep rates at elevated temperatures have hindered its commercialization in structural applications. Much effort has been invested in MoSi2 composites as alternatives to pure molybdenum disilicide for oxidizing and aggressive environments. Molybdenum disilicide-based heating elements have been used extensively in high-temperature furnaces. The low electrical resistance of silicides in combination with high thermal stability, electron-migration resistance, and excellent diffusion-barrier characteristics is important for microelectronic applications.

How is Molybdenum Silicide MoSi2 Powder produced?
Molybdenum disilicide and MoSi2-based materials are usually made by sintering. Plasma spraying can be used to produce dense monoliths and composite forms. The material produced by this method may contain a certain proportion of β-MoSi2 due to its rapid cooling.

Applications of Molybdenum Silicide MoSi2 Powder:
Molybdenum disilicide heating elements can be used for temperatures up to 1800 ° C, in electric furnaces used in laboratory and production environment in the production of glass, steel, electronics, ceramics, and in heat treatment of materials. Molybdenum disilicide is used in microelectronics as A Contact Material.
Heating element
MoSi2 is a conductive silicide that has an oxidation property due to a stable silica layer on its surface at a high temperature.
Although the top MoSi2 element can operate at temperatures up to 1800 ° C, the material is very brittle, which may suffer serious creep during use. However, they have process advantages because they can work under high electrical loads without aging, and will not exhibit increased resistivity during use. They have antioxidant properties in air, oxygen and oxygen-rich atmosphere.
Moreover, they can be used with ammonia, nitrogen, hydrogen, a rare gas, and limited vacuum, but due to the failure of the protective oxide layer, the operating temperature and life can be reduced.
MoSi2 elements are ready-made elements and can be made into a bending or straight form of a variety of sizes. These elements are mainly used in production furnaces and laboratory furnaces in ceramics, glass, steel, electronics and heat treatment industries.
High-temperature structure
Amazingness and high-temperature elasticity make MoSi2 a very promising material for high-temperature applications such as gas turbine engines. Many researchers strive to improve high temperature creep resistance and low-temperature ductility. However, there are no commercially available composites with all preferred features.
