Thick Aluminum Nitride Substrate for RTP Furnace's Sample Holder - EQ-AIN-Holder Orientation 10-14 Resistivity: (2Such unpolished Aluminum Nitride can be placed in the center of holder for holding test samples up to 3" or 5" diam. The excellent temperature uniformity can be achieved in this 3" or 5" diam. area due to the benefit from its high thermal conductivity.
