PBN Tube
Synthesis through the CVD process, Semicorex PBN Tube is an indispensable tool in the arsenal of industries ranging from semiconductors to metallurgy.
The PBN Tube, a flagship composite ceramic offered by Semicorex, is manufactured through the precise process of chemical vapor deposition (CVD). This method involves the reaction of boron trichloride (BCl3) and ammonia (NH3) under conditions of elevated temperature and reduced pressure. This meticulous process facilitates the formation of Pyrolytic Boron Nitride with remarkably high purity levels, prominently featuring total impurities of less than 100 parts per million (ppm). Such purity of Pyrolytic Boron Nitride is critical for applications within the semiconductor industry and vacuum systems.
PBN Composite Ceramic
Unparalleled Purity and Structural Integrity of Pyrolytic Boron Nitride
With a purity that defines excellence, Pyrolytic Boron Nitride stands as an ideal solution for demanding industrial environments. The ultra-high purity ensures that the PBN Tube is resistant to chemical reactions, making this composite ceramic indispensable for applications that require a sterile and uncontaminated environment. The near-perfect layered structure of the PBN Tube imparts it with anisotropic thermal conductivity. This unique property of Pyrolytic Boron Nitride allows the composite ceramic to efficiently conduct heat along specific planes, providing significant advantages in thermal management applications.
Dimensional Precision and Customization of Composite Ceramic
The CVD process not only guarantees purity of Pyrolytic Boron Nitride but also allows for precise control over the PBN Tube’s dimensions. Typically, the wall thickness of PBN Tubes does not exceed 2mm. Although the dimensions of raw PBN blanks are initially constrained by the capabilities of the equipment used in their fabrication, these blanks can be transformed into highly customized shapes tailored to specific requirements. This capability of the composite ceramic is achieved at a competitive cost, ensuring that customers receive products that meet exacting specifications without compromising on affordability.
