What are the properties of aluminum nitride?

Aluminum nitride (AlN) is a covalent, ceramic material known for its exceptional properties. It has a high thermal conductivity, which is about two-thirds that of copper, making it useful in electronics for heat dissipation. It's also an electrical insulator, exhibiting high electrical resistivity. Aluminum nitride is characterized by its high thermal stability, resistance to thermal shock, and excellent mechanical strength. It's chemically inert, resistant to most acids and alkalis, and has a high melting point of approximately 2200掳C. These properties make it suitable for applications in high-temperature electronics, as a substrate for semiconductor devices, and in the automotive industry for heat sinks and other heat management components.
