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

MATERIAL INTRODUCTION

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.

OUR ADVANTAGE

XTL have 7000 square meters work shop

Automatic production line

Longer working life

Reasonable price


All prototype products have to go through 4 checks in the whole process:
1. Raw material inspection
2. In processing inspection
3. Final inspection
4. Outgoing inspection
