PBN Filament Ring

PBN is frequently used to make filament rings to hold Tantalum(Ta) wire in MBE equipment, due to it's high working temperature and vacuum property. The pyrolytic boron nitride rings QSAM could supply are cut from 1mm 2mm or 3mm thick PBN discs with about 10~14" diameter. The diameter of raw material PBN was limited by equipment size but the finished PBN products could be machined to highly customized shape with competitive price cost.

Packaging

As a ceramic material, boron nitride is quite fragile in a lot of cases. The BN insulators are usually hold in plastic bags by vacuum, and protect with heavy foam.
