Boron Nitride Description

Boron nitride ceramics offer excellent heat resistance, thermal stability, and conductivity, making them ideal for heat dissipation and high-temperature insulation applications. Chemically stable and resistant to most molten metals, they also possess self-lubricating properties. While they resist chemical erosion from inorganic acids and water, they start to oxidize above 1,200 ℃ and decompose in a vacuum at around 2,700 ℃. Their maximum use temperature is 900 ℃ in oxidizing atmospheres and up to 2,800 ℃ in inert reduction atmospheres.

Heeger Materials provides ZSBN, a hot-pressed hexagonal boron nitride ceramic with exceptional chemical, electrical, mechanical, and thermal properties. Suitable for various high-performance industrial applications, ZSBN ceramics are available in high-purity forms and can be customized to meet specific industry needs.
