The physical properties of boron nitride materials can be enhanced by adding some other ceramics material, such as ZrO2 (BN-ZS), SiC (BN-SiC), AlN (BN-AlN), or Si3N4 (BN-Si3N4). High-purity boron nitride can withstand higher temperatures than composite/reinforced in an inert atmosphere. However, Boron Nitride Composite ceramic generally has better wear resistance and better performance in the air.
BN-ZS uses zirconium oxide as a bonding agent to improve the product’s thermal shock and wear resistance. It is often used as a separation ring for horizontal continuous casting and a nozzle made of an amorphous strip. These products have stable chemical properties, high thermal shock, and corrosion resistance. They are widely used for molten metal contact.
-Good chemical stability
-Good wear resistance
-High thermal shock stability
