PBN Tubes (Pyrolytic Boron Nitride Tubes) are ultra-high-purity advanced ceramic tubes manufactured using Chemical Vapor Deposition (CVD) to produce a dense, non-porous boron nitride structure with exceptional thermal stability, chemical inertness, and electrical insulation. Compared to conventional hot-pressed boron nitride, PBN offers ultra-low contamination, extremely low outgassing, excellent vacuum compatibility, and superior resistance to thermal shock, making it the preferred material for critical semiconductor and high-temperature processing applications.
PBN Tubes are widely used in semiconductor manufacturing, compound semiconductor crystal growth, molecular beam epitaxy (MBE), vacuum deposition, OLED production, aerospace, vacuum furnaces, analytical instrumentation, and advanced materials research. Their outstanding purity and non-reactive surface minimize contamination while providing reliable performance in aggressive thermal environments.
REG Metals supplies premium-quality Pyrolytic Boron Nitride Tubes in standard and custom sizes with precision machining, tight dimensional tolerances, and superior surface finishes for demanding industrial and laboratory applications.
