Pyrolytic Boron Nitride Ring | PBN Ring

 

Pyrolytic Boron Nitride (PBN) Ring 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. PBN products are extremely pure, as the purity of gas material is easier to be controlled. Typically, PBN products have total impurity of <100 ppm, which means the purity is no less than 99.99%. With such a high purity level, PBN rings are ideal products for semiconductor industries & vacuum system.

With its high density and purity, PBN is becoming a widely used material in vacuum processes. The CVD process give this pyrolytic boron nitride almost perfect layered structure, which leads to anisotropic thermal conductivity, making it an ideal material to make components for furnace & vacuum system.

The pyrolytic boron nitride rings Edgetech Industries could supply, are cut from 1mm, 2mm or 3mm thick PBN rings with about 10~14″ diameter. The diameter of raw material PBN was limited by equipment size but the finished PBN rings could be machined to highly customized shape with competitive cost. Please send us drawing with all details for any customized PBN products.

 

Packaging

 

As a ceramic material, boron nitride is quite fragile in a lot of cases. The Pyrolytic Boron Nitride (PBN) Rings are usually hold in plastic bags by vacuum, and protect with heavy foam.
