PBN Filament Ring Introduction
Manufactured using the chemical vapor deposition (CVD) method, PBN filament rings possess an extraordinary level of purity, easily reaching up to 99.99%. This is attributed to the unique gas-to-solid phase change involved in CVD, which prevents solid impurities from being present in the gas phase and ensures minimal deposition of gaseous impurities during the process. This high purity makes PBN filament rings particularly well-suited for applications that demand strict purity requirements, such as molecular beam epitaxy (MBE).
In MBE equipment, PBN filament rings play a crucial role in supporting MBE crucibles and securing heating filaments. Their compatibility with PBN crucibles ensures a harmonized system that enables reliable and efficient performance. Moreover, the exceptional thermal stability of PBN facilitates uniform heating and minimizes the risk of thermal degradation, making it an excellent choice for demanding MBE processes.
The combination of high purity, thermal stability, and compatibility with PBN crucibles makes PBN filament rings an indispensable component in MBE equipment. By providing a contamination-free environment and reliable support for crucibles and heating filaments, they contribute to the success and precision of MBE processes. Whether in research laboratories or industrial settings, the implementation of PBN filament rings ensures consistent and high-quality results in the fabrication of advanced materials and semiconductor devices.
Our PBN Filament Ring
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.

PBN Filmament Ring Packaging
As a ceramic material, boron nitride is quite fragile in a lot of cases. The PBN filament rings are usually hold in plastic bags by vacuum, and protect with heavy foam.
