Available boron nitride materials for our BN rods
As a supplier of special advanced ceramic materials, QSAM is working together with researching institutions to produce a series of boron nitride material. Except for the pure boron nitride BN99, we also deliver composite boron nitride material with silicon carbide, calcium borate, aluminum nitride and zirconia, to fulfill various of demand for the customers. Our regular pure BN99 boron nitride material balnaced the purity and srength of the material and become the most popular BN material in the market.

Our boron nitride rods
High purity boron nitride rods could withstand higher temperature in vacuum than lower purity and composite boron nitride products. However, the composite materials generally enhanced mechanical properties such as bending strength, and the high temperature performance in air.
Due to the low wetability with metals, boron nitride rod is an ideal material for metal melting works, especially for high purity material metal in vacuum.
As a supplier of solid advanced ceramic materials, QS Advanced Materials could custom make all kinds of rods and other products in about 2 weeks with $200 MOQ. Typical boron nitride rods are smaller than 12" dia x 15" length due to the limitation of our equipment. Other form of boron nitride machined products could be available with drawings.
About other boron nitride brands
Hexagonal Boron Nitride (h-BN) has a hardness of about 4, making it a machinable material. HBN/HBR/HBT originally referred to product codes for other manufacturers and denoted boric oxide or calcium-enhanced boron nitride materials, respectively. QSAM also provides equivalent boron nitride rods with similar performance to HBN, HBT and HBR. While calcium (or zirconium) enhanced HBR (or ZSBN) is the most common composite boron nitride material, we also produce high purity version TPBN (equivalent to HBT) and a range of other composite boron nitrides, such as AlN-BN and SiC-BN.
