High temperature stability: As a heating element for electric furnaces (such as MoSi ₂ heating element), it can be used up to 1800 ° C in air, especially suitable for laboratory and industrial high-temperature furnaces. Advantages: Compared to traditional materials such as silicon carbide rods, it has a longer lifespan and does not require a protective atmosphere.

3. Coating and Protection

Anti oxidation coating: used as a surface coating for refractory metals such as molybdenum and tungsten, to prevent high-temperature oxidation and extend component life. Application scenarios: High temperature resistant components for aircraft engines, rocket nozzles, and glass manufacturing equipment.

4. Electronics and Semiconductors

Integrated circuit: As a gate or interconnect material, it is suitable for high-power devices due to its low resistivity and good thermal stability. Thin film technology: used for thin film resistors and sensors, especially in high temperature or corrosive environments.

5. Composite material reinforcement phase

Toughening effect: As a reinforcing phase in ceramic based composite materials such as SiC and Al ₂ O3, it enhances thermal shock resistance and fracture toughness. Application examples: High temperature wear-resistant components, nuclear reactor structural materials.

6. Catalyst

Catalytic applications: MoSi ₂ and its derivatives exhibit catalytic activity in certain chemical reactions, such as methane reforming and ammonia oxidation, and may be used in the petrochemical or environmental protection fields.
