Pyrolytic Boron Nitride Crucible Description

Pyrolytic Boron Nitride (PBN) Crucible is a highly pure, crystalline form of boron nitride that is produced through a chemical vapor deposition (CVD) process. Compared with standard boron nitride ceramic, PBN crucibles offer significantly higher purity. These crucibles and other PBN products are synthesized directly on molds using the CVD process, involving BCl3 and NH3 at high temperatures and low pressures. This precise method results in PBN products with a total impurity content of less than 100 ppm, equating to a purity level exceeding 99.99%. Due to this exceptional purity, PBN crucibles are highly suitable for use in the semiconductor industry.

Boron nitride, like graphite, exhibits excellent strength at high temperatures. However, high-purity PBN products offer even superior mechanical properties. As the material is formed through the CVD process, the density of PBN products can approach theoretical maximum values. Additionally, PBN products from Advanced Ceramic Materials boast outstanding thermal shock resistance; PBN plates can be heated to over 2000 degrees Celsius and then plunged into water without fracturing.
