Introduction to molybdenum Disilicide Molybdenum diilicide This silicon molybdenum compound, also known by the name molybdenum-silicide, has a molecular composition of MoSi2 with a molal weight of 154.13. It is a gray metal solid. They have properties that are similar to metals or ceramics because the electronegativity of the two types of atoms is close and their radii do not differ much. The melting point can reach as high a temperature as 2030degC and is also conductive. It is possible to form a layer of silicon dioxide on the surface at high temperatures in order to prevent further oxidation. Its gray metallic colour is due to its tetragonal, a-type crystalline structure. Although it has a hexagonal form, the crystal structure is unstable. The b modified crystal structure. Insoluble in many acids, but soluble only in hydrofluoric and nitric acids.
It is used for high-temperature antioxidation coatings, electric heating element films, structural materials as well as reinforcing materials for composite materials.

Applications of molybdenum Disilicide
They are used as high-temperature coatings against oxidation, heating elements with integrated electrode films and structural materials. These products are used in the following industries.
1. Energy and Chemical Industry: Electric heating elements, high temperature heat exchangers for atomic reactors devices, gas heaters, high temperature thermocouples with their protection tubes, melting vessels and crucibles. (Used to smelt sodium, lead, bismuth and other metals).
2. Microelectronics: MoSi2 The refractory metal silicides, Ti5Si3, and others (WSi2, TaSi2, Etc.) are also important candidates for large-scale integrated circuit gates and interconnection lines. They are also important candidates as materials for large-scale interconnection and integrated circuit gates.
3. Aerospace Industry: This coating has been extensively researched and used as an anti-oxidation high-temperature coating. Particularly as a material used for turbine engine parts, such as impellers, blades, combustors and nozzles.
4. Automobile Industry: turbocharger rotors for cars, spark plugs, valve bodies and other engine parts.

What factors influence the service life and performance of molybdenum-disilicide heating components?
1. Fired products. Fired products. Magnetic material industry has a longer available time, and special glass the shortest.
2. Product quality. Product quality is determined by raw material production and manufacturing processes.
3. The quality is important. A high quality stove can extend the life of its components.
4. Surface problems. Long-term usage at 1800degC can cause surface problems, such as bubbles and lumps, which will reduce the life of the rod.
5. Dimensional tolerance. The precise temperature control will be affected directly by the accuracy in the size of hot ends. If there is a small tolerance in the diameter of the hot end, then the impedance and cross-sectional area will also be affected, which will alter the heat generated by the electric heating component. It also affects the uniformity or life of the heating elements in an electric furnace.
6. Furnace operator. The heating element will be damaged if it is overheated or has too much power.
7. Product contamination. The component deteriorates when the protective coating reacts with a product or an atmosphere.
8. Insulation issues. Insulation problems.
9. Mechanical force. Thermal breaks can become brittle and deform if they are placed in the wrong direction.
