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 similar properties to ceramics and metals because the radii and electronegativity of the two types of atoms is not very different. 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. The gray metallic color 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, electrode films integrated, structural materials. Composite materials. Reinforcements for composite materials. Wear-resistant materials. Connecting materials for structural ceramics. These products are used in the following industries.
1. Energy and Chemical Industry: Electric heating elements, heat exchangers for atomic reactors, gas burners, thermocouples at high temperatures and their protective tubes, melting vessels and crucibles.
2. Microelectronics: MoSi2 The refractory metals Si5Si3, WSi2, and TaSi2, among others, are also good 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 widely researched and extensively applied in the aerospace industry 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: turbochargers, valves bodies, spark plugs, and engine parts.

What factors influence the service life and performance of molybdenum-disilicide heating components?
1. Fired products. Fired products. The magnetic material industry is the one with the longest service life, and the special glass industry has the least.
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 hot-end size. 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 even deform if they are placed in the wrong direction.
