PRODUCT INTRODUCTION

Pyrolytic boron nitride (PBN) is a special ceramic material, obtained from special equipment by using chemical vapor deposition process. The pyrolytic boron nitride deposition process, like a "snow": hexagonal boron nitride snow sheet parallel to falls, to a piece of graphite base material, and reaches a certain thickness, the final cooling demolding made.

APPLICATION

1) Electronic Parts - heat sinks, substrates, coil forms, prototypes

2) Boron doping wafers in silicon semiconductor processing

3) Vacuum melting crucibles

4) High precision sealing, brazing, and metallizing fixtures

5) Microwave tubes

6) Horizonatal caster break rings

7) Low friction seals

8) Plasma arc insulators

9) High temperature furnace fixtures and supports
