High Purity Boron Nitride Plates/Discs Description

Similar with graphite, boron nitride ceramic has great strength at high temperature. High purity PBN products have even better mechanical properties. As the solid material is formed by the CVD process, the density of the products could almost reach the theoretical value. PBN products provided by Advanced Ceramic Materials also have great thermal shock resistance. Plates of PBN could be heated to more than 2000 degree and dropped into the water without getting broken.
