Aluminum Nitride Ceramic

Aluminum Nitride or AlN is an extremely thermal conductive ceramic material, as well as being strong thermal radiative and offering an outstanding electrical insulation performance. According to the manufacturing conditions, this capability of aluminum nitride ceramic is used in the fabrication of semiconductor industry devices, electronic substrates, as well as in other areas owing to the development of its applications.

One of the typical application is substrates made of AlN ceramic, which is strongly thermal conduction and has a strong electrical insulation property, moreover, AlN material has the coefficient of thermal expansion nearly identical to that of silicon. Aluminum Nitride (AlN) is heat-resistant, very easily working from low temperature to high temperature.

Another application are ceramic components made of aluminum nitride material. AlN is a well-balanced technical ceramic for a part of a semiconductor manufacturing device, especially with regard to its excellent thermal shock resistance, plasma resistance, and electrical insulation characteristics, and also has a coefficient of thermal expansion that is surprisingly similar to that of silicon wafer.

Due to its excellent thermal, electrical and mechanical properties, aluminum nitride (AlN) ceramics have received extensive attention from engineers and researchers at home and abroad. With the rapid development of modern science and technology, higher requirements are put forward for the properties of the materials used, and this special nitride based ceramic is also widely used in many fields! Although many researchers have made great progress in powder preparation, forming, sintering and other aspects through the unremitting efforts of many researchers over the years, so far, the commercialization of aluminum nitride is not high enough, which also affects nitriding. A key factor for the further development of aluminum nitride AlN ceramics. In order to promote the further development of aluminum nitride research and application, UNIPRETEC has been committed to the development of related work.
