High purity boron nitride is a machinable ceramic and made of the high purity hexagonal BN powder.
DMCERA® High Purity Boron Nitride
High purity boron nitride is a machinable ceramic and made of the highest purity hexagonal BN powder.It can be used in highest temperature (>2200 ºC) in inert or vacuum environments. DMCERA®BN-HB has the high purity and highest density in all of pure BN ceramics. It is easy to machine and we can do as customer’s drawings.
Advantages:
● High purity materials (BN>99.5%).
● Binder-less ceramic.
● Good chemical inertness.
● Highest temperature (2300 ºC in inert).
Applications:
● Boron source of solid diffusion.
● Nozzles for specialty alloys.
● Crucibles for high-purity molten metals.
● Components for semiconductor equipment.
● Setter plate(paving plate) for sintering ceramics.
● Insulators and protective tubes for high-temperature furnaces.
