Boron Nitride Plate Description

Similar to graphite, boron nitride ceramic has great strength at high temperatures. 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 degrees and dropped into the water without getting broken.
