Pyrolytic Boron Nitride (PBN) Ring
PBN1273
New product
PBN rings, reaching 99.999% purity, endure temperatures up to 2300°C in a vacuum without decomposition or gas release. Ideal for high-temperature, vacuum, MBE, and OLED applications, they serve as support frames, insulators, and spacers. Heeger Materials offers top-quality PBN rings at competitive prices, with customized options for purity and dimensions to meet specific requirements.
Please contact us if you need customized services. We will contact you with the price and availability in 24 hours.
