PBN Crucible Introduction

The pyrolytic boron nitride (PBN) crucible offers significant advantages in high-temperature processes due to its exceptional thermal stability, chemical inertness, and excellent heat transfer properties. PBN crucibles are known for their ability to withstand extreme temperatures without deforming or reacting with the materials being processed, ensuring a clean and uncontaminated environment. Additionally, the superior heat conductivity of PBN crucibles enables rapid and uniform heating, promoting efficient and consistent reactions. Because PBN crucibles are manufactured using the CVD method, the h-BN crystals exhibit a perfect layered structure and grow along the surface of the crucible. This ensures uniform thermal conductivity throughout the crucible, which is noticeably different from hot pressing BN or other hot-pressed ceramics. This unique property makes PBN crucibles highly suitable for crystal growth applications. Furthermore, due to the unusual gas-to-solid phase change involved in the CVD process, PBN exhibits exceptionally high purity, easily reaching levels as high as 99.99%. These inherent advantages have made PBN crucibles a preferred choice in industries such as semiconductor manufacturing, metallurgy, and advanced materials research.

Packaging of PBN Crucibles

In order to deliver the fragile PBN materials safe, the crucibles are packed in bag weak vacuum, and heavy foam.
