Product Details

Boron nitride (BN) blanks are usually the raw material to make the other machined parts. It could also directly be applied directly as insulators in some electronic or vacuum equipment with simple machining.

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

QS Advanced Materials supplies pure and enhanced BN blanks in all available dimensions with quick turn around. Typical BN products are smaller than 12" dia x 15" length rod, due to the limitation of our equipment.

Common properties and advantage of boron nitride (compared with the other ceramic materials)

>Low wetability to molten metal
>Relatively high thermal conductivity with low thermal expansion
>Relatively high thermal shock resistance
>Extremely high working temperature with proper inert gas protection (>3000C has been recorded).

As a supplier of special advanced ceramic materials, QSRE 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 BN material with silicon carbide, calcium borate, aluminum nitride and zirconia, to fulfill various of demand for the customers.

*Hexagonal Boron Nitride, or h-BN, with hardness about 4, is a machinable material. HBN/HBR is originally a product code for other manufacture and represents for the boric oxide or calcium enhanced BN material respectively. QSRE is also providing calcium borate enhanced BN blanks with similar performance compared with HBN and HBR. Although calcium (or zirconium) enhanced HBR (or ZSBN) are the most common composite boron nitride material, we also produce a series of other composite boron nitride, such as AlN-BN, SiC-BN

Packaging

As a ceramic material, boron nitride is quite fragile in a lot of cases. The BN insulators are usually hold in plastic bags by vacuum, and protect with heavy foam.
