Product use

Molybdenum silicide powder is a kind of inorganic substance, which belongs to molybdenum-silicon compound. The radius of the two kinds of atoms is not much different, and the electronegativity is relatively close, which is similar to that of metals and ceramics. Molybdenum disilicide has electrical conductivity and a passivation layer of silicon dioxide can be formed on the surface at high temperature to prevent further oxidation. Molybdenum silicide is a key material in high-tech fields, such as high-temperature anti-oxidation coating materials, electric heating elements, integrated electrode films, structural materials, reinforcers for composites, wear-resistant materials, bonding materials for structural ceramics and so on;

（1）Energy chemical industry: electric heating elements, high temperature heat exchangers for atomic reactor installations, gas burners, high temperature thermocouples and their protective tubes, melting vessel crucibles (for melting sodium, lithium, lead, bismuth, tin and other metals);

（2）Microelectronics industry: MoSi₂ and other refractory metal silicide Ti₅Si₃, WSi₂, TaSi₂ are important candidates for gate and interconnect films in large-scale integrated circuits;

（3）Aerospace industry: as a high temperature anti-oxidation coating material has been extensive and in-depth research and application. Especially as materials for turbine engine components, such as blades, impellers, burners, tail nozzles and sealing devices;

（4）Automotive industry: turbocharger rotors, valve bodies, spark plugs and engine parts for automobiles；
