aluminium nitride, thermal conductivity
Aluminum Nitride is one of a few materials which has both high thermal conductivity and electrical insulation. Only a few ceramics possess high thermal conductivity: Beryllium Oxide (BeO) and cubic Boron Nitride (c-BN) are virtually the only other examples. Aluminum Nitride (AlN) is a unique ceramic material that combines high thermal conductivity with high electrical resistivity. This article provides details on how aluminium nitride is produced, key properties and its applications, including microelectronics. Tay a Samani a b f X.Z. Aluminium nitride has the chemical formula AlN. High thermal conductivity about 7 … It is a covalently bonded inorganic compound with a hexagonal wurtzite crystal structure. The thermal conductivity of boron nitride and aluminum nitride particle epoxy-matrix composites was increased by up to 97% by surface treatment of the particles prior to composite fabrication. Ding b N. Khosravian f B. Amin-Ahmadi c Yang Yi d G. Chen e E.C. Thermal properties. Its wurtzite phase (w-AlN) has a band gap of ~6 eV at room temperature and has a potential application in optoelectronics operating at deep ultraviolet frequencies. Neyts f A. Bogaerts f B.K. It has a density of 3.3 g/cm 3 and a molar mass of 40.99 g/mol. Aluminum nitride (AlN) has ultra-high thermal conductivity, excellent electrical insulation, low dielectric loss, thermal expansion coefficient close to silicon, and excellent plasma resistance. the theoretical thermal conductivity of single crystal aluminum nitride (AlN) is 319 W/m-K, whereas, the values measured for polycrystalline AlN ceramics range from 17 W/m-K to 285 W/m- K. Aluminium Nitride products have superior thermal conductivity, high electric insulation, and coefficient of thermal expansion similar to that of silicon (Si). K), and is an electrical insulator. aluminum nitride thermal conductivity for sale - 50 - aluminum nitride thermal conductivity wholesalers & aluminum nitride thermal conductivity manufacturers from China manufacturers. In contrast to most ceramics, aluminium nitride has a very high thermal conductivity.
