Boron Nitride Tube (BN Tube) Description

Boron Nitride, also known as BN, hexagonal boron nitride (H-BN), and hot-pressed boron nitride, is a good self-lubricate ceramic that can withstand high temperature and maintain its lubricating capability in a high vacuum environment. Hexagonal boron nitride (H-BN) behaves similarly to graphite mechanically but offers excellent electrical resistance. Boron Nitride Tube (BN Tube) from Stanford Advanced Materials (SAM) is made from hot-pressed Boron Nitride Blank.

Boron Nitride Tube (BN Tube) Applications

Boron Nitride (BN) Tubes are highly valued for their unique combination of thermal stability, chemical inertness, electrical insulation, and mechanical strength, making them essential in various high-performance applications. In high-temperature furnaces, BN tubes are used as insulating components and heating elements due to their ability to withstand extreme temperatures. They are crucial in semiconductor manufacturing for wafer processing, crucibles, and boats, ensuring purity and preventing contamination. Aerospace and defense applications benefit from BN tubes for thermal management and as ablative materials in rocket nozzles. In chemical processing, BN tubes serve as reactor linings, components, and insulating supports, thanks to their resistance to corrosion and aggressive chemicals. They are also employed in electrical and electronic applications as insulating tubes and heat sinks, enhancing thermal management. BN tubes are used in optical systems for lens supports, in analytical instruments for sample holders and probes, and metal and glass processing as molds and supports. In vacuum and ultra-high vacuum systems, BN tubes provide low outgassing and high thermal stability. Additionally, they are utilized in medical and dental applications for prosthetics and laboratory equipment due to their biocompatibility and resistance to sterilization. Overall, BN tubes play a critical role in advancing technology and performance across a range of industries.
