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 and substrates for high-power electronic devices, helping to dissipate heat efficiently while maintaining electrical isolation. It is commonly employed in the production of integrated circuits, laser diodes, and high-frequency electronic components where thermal management is critical. Its compatibility with semiconductor processing makes it suitable for use in epitaxial growth of gallium nitride layers in optoelectronic devices. Aluminum nitride is also used in harsh environment sensors and as a ceramic component in aerospace and defense applications due to its stability at high temperatures and resistance to thermal shock. Additionally, it finds use in specialized optical components and as a crucible material for handling molten metals and semiconductors.
