Technical Ceramics Manufacturers of
Pyrolytic Boron Nitride Crucible for LEC MBE VGF
We provide custom PBN crucibles and VGF / LEC / Conical / MBE / OLED crucibles.
Pyrolytic Boron Nitride (PBN) VGF Crucible is produced by the CVD process to create its solid body and all the boron nitride crystals grow parallel to the surface on which the vapor is deposited. Due to the nature of the CVD process, thick wall products (>3mm) are usually not available. For PBN VGF crucibles, the 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 a 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 systems.
Hot pressed BN is compacted at temperatures up to 2000°C and pressures up to 2000 psi to form a dense, strong engineering material that is easily machined. It is available in standard and custom hot pressed shapes and has several unique characteristics and physical properties which make it valuable for solving tough problems in a wide range of industrial applications.
As a ceramic material, boron nitride is quite fragile in a lot of cases. The Pyrolytic Boron Nitride (PBN) VGF crucibles are usually held in plastic bags by vacuum, and protected with heavy foam.
