Boron nitride is a machinable ceramic.Boron nitride blank can easily be into ceramic rod, ceramic ring, ceramic bushing, ceramic washer and complex shapes.
DMCERA®Boron Nitride Blank
Boron nitride,CAS:10043-11-5, is an advanced ceramic material. It has high thermal conductivity and microwave penetration performance.It can be used as a radar transmission window in the electronics industry. Hexagonal boron nitride products can be used as high-temperature metal smelting crucibles, heat-resistant materials, heat sinks and heat-conducting materials due to their high melting point, small thermal expansion coefficient, and stability to almost all molten metals.
Boron nitride is a machinable ceramic. Boron nitride blank can easily be machined into ceramic rod, ceramic ring, ceramic bushing, ceramic washer and complex shapes.
Applications:
● Nozzles in amorphous strip Industry
● Break rings in horizontal continuous casting
● Side dams in thin-strip casting process
● Insulators for high-temperature furnaces
