Silicon carbide ceramic substrates not only have excellent mechanical properties at room temperature, such as high bending strength, good oxidation resistance, corrosion resistance, good wear resistance, and low friction coefficient, but also have high-temperature mechanical properties, especially strength and creep resistance. It is also the best known ceramic material. Especially in industrial fields such as petrochemicals, microelectronics, aerospace, and automobiles, it has been widely applied.

Application of Ceramic Substrate

1. Ceramic substrates have the advantages of high thermal conductivity, low coefficient of expansion, high strength, high temperature resistance, chemical corrosion resistance, and low dielectric loss, making them ideal materials for large-scale integrated circuit heat dissipation substrates and packaging.

2. High hardness, surpassing traditional alumina, can be used for new wear-resistant ceramic materials.

3. By utilizing the optical properties of aluminum nitride, it can be used as an infrared window. Thin films can be used to make high-frequency piezoelectric components, ultra large scale integrated circuit substrates, etc.

4. It is heat-resistant, resistant to molten metal erosion, acid stable, and can be used as a crucible and casting mold material for melting metals such as aluminum, copper, silver, and lead.

Due to the excellent performance of silicon nitride ceramics, they have been widely used in many industrial fields and have many potential applications.
