Aluminum Nitride (AlN) Ceramics

Aluminum Nitride Description

aluminum nitride ceramicsAluminum nitride, AlN, is a white ceramic material which has a density of 3.26g/cm3. AlN was first synthesized in 1877, but it was not until the middle of the 1980s that its potential for application in microelectronics was realized. Due to its high thermal conductivity and great electrical insulation, aluminum nitride was used in microelectronic industries. Metallization methods are available to allow aluminum nitride to be used in electronics applications similar to those of alumina and beryllium oxide.

Compared with aluminum, which is the traditional technical ceramic material, aluminum nitride has better thermal conductivity and even higher hardness. 

Advanced Ceramic Materials is a leading supplier of ceramic materials. We offer aluminum nitride products of high purity and with competitive price.
