Silicon nitride high thermal conductivity substrates are suitable for use in high temperature environments, such as heat exchangers, combustion chamber linings or other areas where lightweight and high-strength materials are required. In addition, the chemical stability and low thermal expansion coefficient of silicon nitride make it also very useful in semiconductor manufacturing, especially when dealing with high-temperature processes. Their ultra-thin design not only reduces weight, but also allows for efficient use in compact Spaces, providing superior mechanical and thermal properties.

Product advantages of silicon nitride high thermal conductivity substrate:

Ultra-thin design: This design not only reduces the weight of the material, but also allows for efficient use in compact Spaces, increasing the flexibility and overall efficiency of the device design.

High mechanical strength and hardness: Silicon nitride's high hardness (1500 Hv0.5) and elastic modulus (290 GPa) ensure structural integrity and stability under extreme conditions.

Excellent thermal performance: Low coefficient of thermal expansion (3.1×10-6/℃) makes it stable in an environment with drastic temperature changes, suitable for use as the lining of heat exchangers and high temperature furnaces.

Chemical stability and corrosion resistance: Silicon nitride is highly resistant to a variety of chemicals and is suitable for use in chemical treatment environments.
