Pyrolytic Boron Nitride (PBN) Crucible Introduction:
Boron nitride 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 ALB 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.
Compared with normal boron nitride ceramic, pyrolytic boron nitride (PBN) has much better purity level. PBN crucibles 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 of PBN products made from CVD process have 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.
