Aluminum nitride is widely used in electronic and semiconductor applications due to its excellent thermal conductivity and electrical insulation properties. It serves as a key material in heat sinks, substrates, and packaging for high-power and high-frequency devices such as LEDs, laser diodes, and RF components. Its ability to efficiently dissipate heat while remaining electrically insulating makes it ideal for power modules in automotive and industrial electronics. Additionally, aluminum nitride is used in optoelectronics and as a component in piezoelectric devices due to its favorable acoustic properties. It also finds use in harsh environments, including aerospace and defense systems, where thermal stability and reliability are critical.
