Pyrolytic Boron Nitride Crucible Description

Pyrolytic boron nitride crucible (PBN Crucible) from SAM has a much better purity level compared with normal boron nitride ceramic materials. Using BCl3 and NH3 as raw materials, pure pyrolytic boron nitride crucibles can be prepared by chemical vapor deposition (CVD) process at high temperature and low pressure, because the purity of steam is easier to control. Most PBN products made by the CVD process have less than 100 ppm total impurities, which means purity is better than 99.99%. High purity PBN products have excellent mechanical properties such as high electrical resistance and good thermal conductivity.

Pyrolytic Boron Nitride Crucible Application

Pyrolytic boron nitride 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. As the solid material is formed by the CVD process, the purity and density of the PBN products could almost reach the theoretical value. PBN crucibles with such high purity are ideal products for the semiconductor industry. 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.
