AlN substrates offer numerous advantages, making them highly sought after across various applications. Here are some of the key characteristics of AlN substrates:

▽ Superior Thermal Conductivity
AlN exhibits exceptional thermal conductivity, surpassing many other engineering ceramics. This makes AlN substrates ideal for applications requiring efficient heat dissipation, such as high-power electronic devices and LED packaging.

▽ Excellent Electrical Insulation
With outstanding electrical insulation properties, AlN is well-suited for electronic devices that require high insulation performance, including high-frequency circuits and power modules.

▽ Low Thermal Expansion Coefficient
AlN has a thermal expansion coefficient similar to that of silicon, which is highly valuable in electronic packaging applications as it helps reduce mechanical stress caused by thermal expansion mismatches.

▽ High-Temperature Stability
AlN maintains its physical and mechanical properties in high-temperature environments, making it suitable for high-temperature electronic devices and aerospace applications.

▽ Strong Chemical Stability
AlN demonstrates excellent stability in various chemical environments, making it suitable for applications that require corrosion resistance.

▽ Low Dielectric Loss
With low dielectric loss, AlN is ideal for manufacturing high-frequency electronic devices such as microwave and RF circuits.

▽ Good Mechanical Performance
While AlN has relatively lower hardness, its higher toughness reduces the risk of fracture under mechanical stress. This makes AlN substrates suitable for applications requiring resistance to mechanical vibration and impact.

▽ Biocompatibility
AlN is biocompatible in certain biomedical applications, making it a suitable material for biosensors, medical instruments, and related technologies.
