FUNCMATER provides high-purity aluminum nitride powder exhibits excellent thermal conductivity, a high rate of electrical insulation, and thermal expansion properties similar to various kinds of semiconductors, making it an optimum material for sintered bodies. AlN is primarily used as heat-dissipation materials for electronic components that perform unstably when heated, such as semiconductors.
