Description of Pyrolytic Boron Nitride Crucibles

Compared with normal boron nitride ceramic, pyrolytic boron nitride (PBN) has a 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.  

Similar to graphite, boron nitride has great strength at high temperatures. High purity PBN products have even better mechanical properties such as high electrical resistance and good thermal conductivity. 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 Stanford Advanced 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.

Our PBN crucibles are traditionally used to vaporize a variety of materials including Gallium (Ga) and Aluminium (Al) for epitaxial growth compound semiconductors due to their high purity, anisotropic thermal properties, chemical inertness, thermal stability, and thermal shock resistance.
