Pyrolytic Boron Nitride Conical Crucible

 

Pyrolytic Boron Nitride (PBN) Conical Crucible is produced by CVD process to create its solid body and all the boron nitride crystals grow parallel to the surface of which the vapor is deposited on. Due to the nature of CVD process, thick wall products (>3mm) is usually not available. For PBN Conical crucibles, typical thickness is 0.8~1.5mm.

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 products 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 crucibles for crystal growing. PBN conical shape crucibles are frequently consumed in crystal growth process.

The pyrolytic boron nitride crucibles EDGETECH could supply are custom produced from our CVD furnace with high purity material. Dimensions of PBN crucibles are limited within 12″ Dia. x 12″ H, by equipment size.

We provide custom PBN crucibles and VGF / LEC / Conical / MBE / OLED crucibles.

 

Packaging

 

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