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.

Boron nitride can be long-term used at 1800 degrees under vacuum atmosphere. With gas protection,

 

Boron Nitride can be used at 2100°. Boron Nitride is with high thermal shock resistance, no cracks under

extreme cold & high temperature. If you take out Boron Nitride from 1000 degree furnace and colding it

within short minutes. It still won't break even repeat this test with 100 times.

Properties

1. High thermal conductivity
2. Good thermal shock resistance
3. Low thermal expansion
4. Exceptional heat resistance
5. Good chemical Inertness
6. High electrical resistance
7. High volume resistivity
8. Low dielectric constant and loss tangent
9. Excellent machinability

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
