Boron Nitride Composite Ceramic BN-ZS

Compositions: BN+SiC+ZrO2


Boron Nitride Composite Ceramic BN-ZS


Boron nitride material could be physically enhanced by adding some other ceramics, such as CaO (HBN), ZrO2(BN-ZS), or AlN (AlN-BN), high purity boron nitride could withstand higher temperatures in an inert atmosphere than the composite/enhanced ceramics. However, the enhanced BN usually has better wear resistivity and better performance in the air.

Boron nitride composite ceramic BN-ZS, using silicon carbide and zirconia as a bonding agent, improves the thermal shock resistance and wear resistance of the product. It is commonly used as a separate ring for horizontal continuous casting and a nozzle made of amorphous ribbon. These products have stable chemical properties, high thermal shock resistance, and high corrosion resistance. They are widely used in molten metal contact.
