More info
Boron nitride composite ceramic ZSBN, using carbide and zirconia as a bonding agent, improves the thermal shock resistance and wear resistance of the merchandise. It's commonly used as a separate ring for horizontal continuous casting and a nozzle made from amorphous ribbon. These products have stable chemical properties, high thermal shock resistance, and high corrosion resistance. they're widely utilized in molten metal contact.
- Chemical stability
- Good wear resistance
- High thermal shock stability
