PBN Crucibles, Pyrolytic Boron Nitride Description

Pyrolytic Boron Nitride Crucibles (PBN Crucibles) from SAM have 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 of 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.
