Detailed introduction of aluminum nitride
Aluminum nitride is a ceramic insulator that gives it high heat transfer capability, leading to its widespread use in microelectronics. Unlike beryllium oxide, aluminum nitride is non-toxic. Aluminum nitride, treated with metal, can replace alumina and beryllium oxide in a large number of electronic instruments.
