Aluminum Nitride (AlN)

Aluminum Nitride (AlN) is a hard white crystalline solid with high thermal stability (Melting point of 2200ºC), high resistance, and low porosity. It is a ceramic with high–thermal conductivity and a low thermal expansion coefficient. It is used as an electronic substrate due to its high electrical resistance, low dielectric constant, and wide bandgap.

Typical Applications

Aluminum Nitride (AlN) is used for semiconductor equipment and applications, as an electronic substrate, and in the production of sialons. It is used in wide-bandgap semiconductors for wireless communications and power-industry applications, and in microelectronic devices on jet engines. It is also used in electronic, light, and field-emission devices. It is also used as an electrically insulating material.
