It is stated that DLC AlN has 10-15 times greater Thermal Conductivity 100- 220(W/mK), 50-75% greater bending strength, and a coefficient of Thermal Expansion more closely matching that of silicon. A light tan/ white to gray powder which can be fired to translucence

Aluminum Nitride Typical Chemical Properties Available:

Single crystals, sintered pieces, rods, targets, pellets, whiskers, grinding media, coarse grains for fillers, and fine powder
Granules and powder are available from as coarse as 60 mesh (250 µm) and finer down to a 0.5 µm product. The finest commercial grade available in tonnage lots has an average agglomerated particle size of approximately 1.8 microns.

Typical Applications:

High thermally conductive ceramics, translucent ceramics, Si-Al-O-N compounds, high temperature materials, additives, heat sinks, power and multichip modules, refractories, ceramic armor, break rings, coatings, insulators, heat radiation plates, optoelectronic devices, metal matrix composites, thermally conductive filler, IC packages and substrates
