FEATURES & ADVANTAGES
●A unique formulation process and optimization of structure, BN-E have thermal shock resistance, corrosion resistance, creep resistance performances.
●Adopting international advanced hot-pressing sintering process, fine structure, high purity, with superior physical properties.
●Non-reaction, non-wet and non- contamination by almost all molten metal in high temperature. BN-E is widely used in a variety of molten metal contact applications.
TYPICAL APPLICATIONS
●Boron nitride continuous casting break rings
●Boron nitride side dams for thin-strip casting
●Boron nitride nozzles for amorphous and nanocrystalline.
●Nozzles for powder metal atomization
●PENSC can produce all kinds of bn ceramics based on customer’s requirements
