XTL sintyron high quality pbn conical oled vgf lec mbe crucible

Pyrolytic boron nitride belongs to hexagonal crystal, is a special ceramic material, the purity can reach 99.999%, acid and alkali resistance, oxidation resistance, good thermal conductivity, can be processed. The deposition process of pyrolytic boron nitride is like "falling snow ", and the hexagonal small snow flakes of boron nitride fall on the graphite matrix material one piece in parallel, reaching a certain thickness, and finally made of cooling and stripping.

PBN ceramic (pyrolytic boron nitride, pyrolytic BN) is a kind of advanced ceramic, can be produced with 99.99% purity by the forming method of chemical vapour deposition (CVD), no need to go through the traditional hot pressing sintering process. PBN ceramic has high purity, chemical inertness, thermal stability, low outgassing, non-wetting characteristics, and long lifetime, it is the ideal material for furnace, electrical, microwave, and semiconductor components.
