Boron nitride is a high-temperature ceramic that has a structure similar to graphite. Our portfolio of hot-pressed solid materials includes pure hexagonal boron nitride and composites suitable for applications requiring excellent thermal properties combined with electrical isolation. Easily machinable and fast availability make boron nitride an outstanding choice for large-scale prototypes requiring its unique properties. The BN components portfolio features various high-purity hexagonal boron nitride (hBN) materials. These materials are used in various applications, including high-temperature electrical insulators, refractory components, semiconductor equipment, and crucibles. With the boric oxide binder, BN4000 has the highest mechanical properties of all the pure hBN products. BN4000 can be used in a variety of electrical insulators and general-purpose applications. The hygroscopic nature of boric oxide makes this material susceptible to moisture pick-up. Applications: high-temperature electrical insulators, crucibles, ion implantation systems, powdered metal spray nozzles, and setter plates. BN5000: The calcium borate binder in BN5000 makes this the most versatile of all the hBN grades due to the reduced susceptibility to moisture pick-up. BN5000 can be used in various higher-temperature applications requiring lower thermal expansion and higher thermal shock resistance. Applications: thermocouple protection tubes, crucibles, electrical insulators, glass manufacturing rolls, and support plates. BN6000: Having one of the lowest binder contents of all the hBN materials, BN6000 offers an economical alternative to the high-purity grades. BN6000 is an excellent general-purpose grade for higher temperature applications requiring vacuum or inert environments in sizes up to ø300mm x 400mm long. Applications: electrical insulators, thermocouple protection tubes, crucibles and rollers for molten glass and metals, casting nozzles for non-ferrous metals, channel and pump components for molten metals.
