Boron Nitride Nozzle

High purity boron nitride nozzles could withstand higher temperature in vacuum than lower purity boron nitridenozzles. Although we usually claim the maximum working temperature as 2500°C, there's record to use our material at 3000+ °C. Due to the lowwettabilitywith metals, boron nitride tubes is an ideal material to handle molten metals, especially for high purity material metal in vacuum.
Hexagonal Boron Nitride, or h-BN, with hardness about 4, is a machinable material. As the sintering of this material is not quite easy, it requires about 1900°C if it is hotpressed without any additive(usually boron oxide) Our boron nitridenozzleswould have similar performance with Saint Gobain's AX5 series made products.
