What is Aluminum nitride? Aluminium nitride (AIN) is a covalently bonded compound, a covalent crystal, belongs to the diamond nitride, hexagonal crystal system, fibre and zinc mineral type crystal structure, non-toxic, the appearance is white or grey white. Relative density 3. 26; Mohs hardness 9; coefficient of thermal expansion 4. 8410-6 K-1 (25-600℃); thermal conductivity 30. IW/(m.K) (200℃); resistivity 2 iolln, -cm (25℃); permittivity 8.15. Room temperature intensity is high, and the intensity decreases slowly with increasing temperature. With good thermal conductivity and a small thermal expansion coefficient is a good heat impact resistance material. It has excellent heat and shock resistance. The thermal conductivity of AIN is 2~3 times that of A12 03, and the intensity is higher than A1z Oa at thermal pressure. Aluminium nitride has good corrosion resistance to A1 and other molten metals, gallium arsenide, especially molten A1 liquid, and excellent electrical insulation and dielectric properties. However, the high-temperature oxidation resistance of aluminium nitride is poor, which is easy to absorb moisture and hydrolysis in the atmosphere, and the wet air, water or aqueous liquid contact produces heat and nitrogen and rapid decomposition. At 2516℃ decomposition, the thermal hardness is very high and does not soften the deformation even before the decomposition temperature.
Main uses of Aluminum nitride Rereport that most research today is developing a light-emitting diode based on a semiconductor (gallium nitride or alloy gallium nitride) operating on ultraviolet light, with a wavelength of 250 nanometers. In May 2006, it was reported that an inefficient diode could emit light waves at a wavelength of 210 nm. An energy gap of 6.2 eV on a single aluminium nitride crystal was measured by vacuum UV reflectance. Theoretically, the energy gap allows the passage of some waves at a wavelength of about 200 nm. But in commercial practice, a lot of difficulties need to be overcome. Aluminium nitride is used in photoelectric engineering, including an electric induction layer in the optical storage interface and electronic matrix, wafer carrier at high thermal conductivity, and for military purposes. In addition, aluminium nitride ceramics is a new type of high-technology ceramics. Aluminium nitride substrate has extremely high thermal conductivity, is non-toxic, has corrosion resistance, high-temperature resistance, and good thermal chemical stability, etc. It is the ideal packaging material, heat dissipation material, circuit components and interconnection line carrier for large-scale integrated circuits, semiconductor module circuits and high-power devices. Also, to improve the thermal conductivity and mechanical properties of polymer materials, aluminium nitride ceramics can be used for smelting of nonferrous metals and semiconductor materials, gallium arsenide crucible, thermocouple protection pipe, high-temperature insulation, microwave dielectric materials, high-temperature resistance, corrosion resistant structure ceramics and transparent aluminium nitride microwave ceramic products, used as high thermal conductivity ceramic production raw materials and resin filler, etc. Aluminium nitride is an electrical insulator with good dielectric properties. The aluminium nitride coating on the surface of gallium arsenide protects it from ion injection during annealing.
