    High purity boron nitride tubes could withstand higher temperature in vacuum than lower purity boron nitride tubes. Although we usually claim the maximum working temperature as 2500C, there's record to use our material at 3000+ C. Due to the low wettability with metals, boron nitride is an ideal material to handle molten metals, especially for high purity material metal in vacuum.
