Aluminum Nitride

This solid nitrate of aluminum is an excellent electrical insulator and has a high thermal conductivity considering it is an electrically insulating ceramic. Stable at high temperatures & resistant to most molten salts this material is synthesized by the carbothermal reduction of Aluminum Oxide (Al₂O₃) in a nitrogen or ammonia environment, or by the direct nitridation of the aluminum. Aluminum Nitride is commonly etched with a Chlorine Gas (Cl₂) based reactive etch, and will dissolve in mineral acids slowly through grain boundary attack. Optically AlN is transparent in the ultraviolet and visible regions and can be used in various optical applications. In electronics, Aluminum Nitride is used as a heat sink, insulator, and even as the substrate for electronic circuits.

SCI uses our hot presses to ensure a dense, technical-grade material for use in thin-film deposition.
