Aluminum nitride is an excellent comprehensive performance new ceramic materials having good thermal conductivity, a series of excellent features reliable electrical insulation, low dielectric constant and dielectric loss, as well as with non-toxic silicon matches the coefficient of thermal expansion, which is considered to be a new generation of high integration degree of the semiconductor substrate and an electronic device package ideal material, drawing the extensive attention from researchers at home and abroad.
The features of Nano aluminum nitride vary from many ways. Nano-aluminum nitride has high purity, small particle size distribution, surface area, low high surface activity, bulk density, and good injection molding properties. It can be used for the manufacture of the device, which can reduce the sintering temperature to improve the dimensional stability, high hardness components, high elastic modulus, having a high dielectric constant and low dielectric loss, good thermal conductivity, oxidation resistance, and low coefficient of thermal expansion (similar to silicon). For composite materials, it is good matching with semiconductor silicon, interface compatibility, and can improve the mechanical properties and thermal conductivity of the dielectric properties of the composites.
Nano aluminum nitride main purposes: nano aluminum nitride is mainly used to manufacture integrated circuit substrates, electronic components, optical devices, radiators, hot crucible; fabrication of metal matrix and polymer matrix composites, especially in high temperature sealing and adhesive electronic packaging materials have excellent prospects. Also nano aluminum nitride is also used in non-ferrous metal smelting and semiconductor material gallium arsenide crucible, evaporation boat protective tube, thermocouple, high temperature insulation, microwave dielectric materials, high temperature and corrosion-resistant aluminum nitride structural ceramics and transparent microwave ceramics, as well as the current application in PI resin, mica thermal insulation, thermal grease, insulating paint and thermal oil.
