Boron Nitride is a kind of advanced synthesis ceramic that was sintered at a high temperature and high pressure by BN powder. It has many excellent properties including high-temperature resistance, high thermal conductivity, easy machining, and good lubricity, making BN an outstanding material.
Boron nitride composite ceramic BN-SZ, 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.
