Aluminum Nitride Sheet Description

Alumina nitride sheets are made of high-purity aluminum nitride ceramics. AlN is a light grey or white ceramic material that has a density of 3.26g/cm3. Due to its high thermal conductivity and great electrical insulation, AlN was used in microelectronic industries. Surface oxidization happened in the air even at room temperature, however, the layer can protect the material up to 1370 C. Metallization methods are available to allow aluminum nitride to be used in electronics applications similar to those of alumina and beryllium oxide.

The hardness of aluminum nitride ceramic sheets is even higher than alumina, the traditional technical ceramic, making it an ideal material for applications that require good wear resistance.

Aluminum Nitride Sheet Advantage

Aluminum nitride ceramic sheet has the following advantages:

* Very high thermal conductivity (> 170 W/mK)
* High electrical insulation capacity (>1.1012Ωcm)
* Strength according to the double ring method >320 MPa (biaxial strength)
* Low thermal expansion 4 to 6x10-6K-1(between 20 and 1000°C)
* Good metallization capacity

Aluminum Nitride Sheet Applications

AlN sheets are used in the following applications:

* Opto-electronics;
* Dielectric layers in optical storage media;
* Electronic substrates, chip carriers where high thermal conductivity is essential;
* Military applications.
