Description:

Boron Nitride (BN), also known as hexagonal boron nitride (h-BN) or hot-pressed boron nitride, is a unique self-lubricating ceramic capable of withstanding extremely high temperatures while maintaining its lubricating performance even in high-vacuum environments. This makes it an exceptional material for applications that demand both thermal stability and reliable performance under extreme conditions.

At GESmaterials, our BN crucibles are manufactured from hot-pressed boron nitride blanks, ensuring excellent purity, density, and durability. Hexagonal boron nitride exhibits mechanical behavior similar to graphite, offering easy machinability and high thermal conductivity, but with the added advantage of outstanding electrical insulation. These combined properties make BN crucibles ideal for use in semiconductors, metallurgy, crystal growth, and high-temperature material processing, where both precision and reliability are essential.

Applications:

Boron Nitride (BN) ceramics are advanced materials that combine high thermal stability, excellent corrosion resistance, and outstanding electrical insulation. They are capable of withstanding extremely high temperatures, even in high-vacuum environments, while maintaining reliable performance. These unique properties make BN ceramics an indispensable choice across various high-tech and industrial applications.

Typical uses of BN ceramics include crucibles for crystal growth, break rings for horizontal casting machines, insulators for high-temperature furnaces, electrical insulators in vacuum systems, and feedthrough components for high-voltage equipment. With their combination of machinability, thermal shock resistance, and chemical inertness, BN ceramics from GESmaterials provide reliable solutions for industries that demand both durability and precision under extreme operating conditions.
