Pyrolytic Boron Nitride (PBN) Support & Clamping Rod

The Hidden Threat in High-Vacuum Chambers

Engineers operating MOCVD, MBE, and CVD equipment know that achieving a pristine Ultra-High Vacuum (UHV) is difficult. Often, vacuum levels drop unexpectedly at high temperatures due to internal structural components releasing trapped gases. Upgrading standard fixtures to a high-purity PBN support rod is the definitive solution to maintain process integrity.

1. Eliminating Outgassing in High-Temperature Experiments

At temperatures above 1200°C, ordinary alumina or zirconia structural rods will inevitably outgas due to the binders used in their manufacturing process. Telite Ceramics utilizes a Chemical Vapor Deposition (CVD) method to manufacture every pyrolytic boron nitride rod. With a guaranteed purity of ≥99.99% and zero binders, it will not release any impurities, making it the perfect UHV ceramic support for highly sensitive plasma and semiconductor environments.

2. The Dual Challenge of Support and Thermal Management

Internal components face severe thermal shock during rapid heating and cooling cycles. Because PBN possesses unique thermal anisotropy, it effectively diffuses heat while maintaining exceptional mechanical resilience. When utilized as a PBN clamping rod, it easily withstands thousands of thermal shock cycles without micro-cracking, greatly extending the lifespan of your chamber fixtures.

3. Precision CNC for Complex Configurations

Research applications often require highly specific and complex geometries. Whether you need threaded sections, flange mounts, or perforated supports, Telite Ceramics can machine any custom PBN fixture to exact tolerances. Our advanced milling process guarantees clean, non-shedding edges, allowing the parts to be deployed directly into cleanroom environments.
