Product Overview:
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.
Main features:
1.Color ivory white to orange-brown, non-toxic, non-porous, easy to process.
2.Purity up to 99.99%, dense surface, air tightness.
3.High temperature strength with increasing temperature, 2200 °C reaches the maximum value.
4.Acid, alkali, salt and organic reagents, high temperature, and the vast majority of the molten metal, semiconductor material is not moist, not reaction.
5 Good thermal shock resistance, good thermal conductivity, low thermal expansion coefficient.
6 High resistance, high dielectric strength, a small dielectric constant, and low magnetic loss tangent, and having a good permeability of microwave and infrared properties.
7. Performance of the mechanical, thermal, electrical, and so there is a clear anisotropy.
