The temperature resistance of boron nitride tubes depends on the usage environment. In inert gas or vacuum environments, our boron nitride tubes can operate stably at 1800°C for long-term use, with short-term peak temperature resistance up to 2000°C. In oxidizing atmospheres, the recommended use temperature should not exceed 1000°C, as prolonged exposure at higher temperatures will cause slow oxidation. In practical applications, we recommend customers select appropriate operating temperatures based on specific usage environments and consider the impact of thermal cycling conditions on material lifespan.
Compared to aluminum oxide tubes, boron nitride tubes have several significant advantages: First, the thermal conductivity of BN tubes is much higher than that of aluminum oxide, making them perform better in high-temperature heat dissipation applications; Second, BN tubes have excellent thermal shock resistance, able to withstand rapid temperature changes without cracking; Third, boron nitride does not wet with most molten metals, making it particularly suitable for metal smelting and processing applications; Additionally, BN tubes have self-lubricating characteristics and better machinability, making them easier to precision machine to specific dimensions.
Yes, boron nitride tubes are very suitable for high vacuum environment applications. Our BN tubes have low outgassing rates and high temperature stability, maintaining excellent performance in vacuum environments. In vacuum furnaces, semiconductor manufacturing equipment, and research devices, BN tubes are commonly used as heat shields, heating element supports, and hot zone components. We can also provide surface treatment optimization according to customers’ special vacuum application requirements, further reducing outgassing rates and ensuring compatibility in ultra-high vacuum systems.
