Aluminum Nitride Characteristics: 

Aluminum Nitride Crucible with excellent thermal , mechanical and electrical properties, such as High thermal conductivity, low dielectric constant, linear expansion coefficient matched with silicon, excellent electrical insulation, low density, non-toxic, strength higher. With the extensive development of microelectronic devices, high thermal conductivity aluminum nitride ceramics as matrix materials or packaging materials are widely used.

Aluminum Nitride, formula AlN, is a newer material in the technical ceramics family, and a covalently bonded material with hexagonal crystal structure.AlN has excellent thermal, mechanical and electrical properties, such as high thermal conductivity, low dielectric constant, high electrical resistivity, low density and a thermal expansion coefficient that matches well with that of silicon.
