Product Description

 

Hexagonal Boron Nitride has a microstructure similar to that of Graphite. In both materials this structure, made up of layers of tiny platelets, is responsible for excellent machinability and low-friction properties. we called hexagonal boron nitride (HBN) or white graphite.

Applications

1. Electronic parts - heat sinks, substrates, coil forms, prototypes
2. Vacuum melting crucibles
3. CVD crucibles
4. Microcircuit packaging
5. Sputtering targets
6. High precision sealing, brazing, and metallizing fixtures
7. Microwave tubes
8. Horizontal caster break rings
9. Low friction seals
10. Plasma arc insulators
11. High temperature furnace fixtures and supports

 

 

Advantage:

 

1. Easily machine to desired shape
2. Excellet heat resistance
3. Low thermal expansion
4. Outstanding electrical insulation
5.High wet resistance molten metals, slags and glass
6. Extreme corrosion and wear resistance
