1. Aluminum nitride ceramics are a new type of high-tech ceramics. Aluminum nitride ceramic substrate has extremely high thermal conductivity, non-toxic, corrosion resistance, high temperature resistance, good thermochemical stability, etc. It is an ideal packaging material and heat dissipation for large-scale integrated circuits, semiconductor module circuits and high-power devices. Materials, circuit components and interconnect wire carriers. It is also the best additive to improve the thermal conductivity and mechanical properties of polymer materials. Aluminum nitride ceramics can also be used as crucibles for melting non-ferrous metals and semiconductor materials gallium arsenide, thermocouple protection tubes, high-temperature insulators, microwave dielectrics Materials, high temperature resistant, corrosion resistant structural ceramics and transparent aluminum nitride microwave ceramic products are used as raw materials for the production of high thermal conductivity ceramics and resin fillers. Aluminum nitride is an electrical insulator with good dielectric properties. The aluminum nitride coating on the GaAs surface protects it from ion implantation during annealing.
2. Used as raw materials for high thermal conductivity ceramics, raw materials for AlN ceramic substrates, resin fillers, etc.
