Boron Nitride Tubes

High-purity boron nitride tubes offer greater temperature resistance in a vacuum than lower purity ones. Our materials can typically withstand temperatures up to 2500°C, but they have been used at even higher temperatures exceeding 3000°C. Due to its low wettability with metals, boron nitride is an excellent material for handling molten metals, particularly for high-purity metals in a vacuum. Our equipment can produce typical boron nitride tubes no larger than 12" in diameter and length. Longer boron nitride tubes can be created by connecting multiple tubes via flat or threaded joints. Drawings can be provided for other forms of boron nitride tubes.
HBN/HBR originally originated as a product code by Momentive Performance Materials, where it refers to boricoxide or calcium enhanced boron nitride material. At Amerigo Scientific, we offer our own calcium borate enhanced boron nitride, which delivers comparable performance to HBN and HBR. While the widely used composite boron nitride materials often include calcium (or zirconium) enhanced HBR (or ZSBN), we also provide a series of other composite boron nitride options. For instance, we manufacture materials such as AlN-BN and SiC-BN. These composite variations offer specific properties and performance characteristics, expanding the range of applications where boron nitride can be effectively utilized.
