PBN Strip Description

Compared with normal boron nitride ceramic, pyrolytic boron nitride (PBN) has a much better purity level. PBN strips and other pyrolytic boron nitride products are synthesized on the mold by chemical vapor deposition (CVD) process, with BCl3 and NH3 at high temperature and low pressure. The PBN products are extremely pure, as the purity of vapor is easier to be controlled. Most PBN products made from the CVD process have a total impurity of less than 100 ppm, which means the purity is better than 99.99%. With such a high purity level, PBN crucibles are ideal products for semiconductor industries.

Similar to graphite, boron nitride 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.
