Pyrolytic Boron Nitride (PBN) OLED 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. OLED crucible is a type of PBN crucible used in OLED and CIGS evaporation technology. Due to its ultra-high purity, chemical inertness, excellent high-temperature resistance, and high-temperature stability, it is widely used in metal and semiconductor evaporation.

Packing

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