Polished ceramic substrates of alumina and AlN

Polished and Lapped Ceramic Substrates

Polished ceramic, quartz, high dielectric, sapphire, glass, fused silica, AlN and numerous other hard materials can be shipped from stock.

Aluminum Nitride (AlN) features a high thermal conductivity of 175 W/mK, excellent dielectric properties, and a low thermal expansion similar to silicon. These characteristics make AlN ideal for electrically insulating nontoxic substrate material for hybrid, power and microwave electronics applications.
