Pyrolytic Boron Nitride (PBN) VGF Crucible
PBN1275
New product
PBN crucibles are currently the most ideal containers for compound semiconductor single crystal growth. The main methods of compound semiconductor single crystal growth are liquid seal direct pulling (LEC), horizontal Brillman method (HB) and vertical Brillman method (VB and VGF), and the corresponding PBNs are LEC crucible, VB crucible and VGF crucible, etc.

More info
VGF is the main technology for GaAs and InP compound semiconductor single-crystal growth in the world.
A pyrolytic boron nitride (PBN) VGF crucible is the ideal vessel for single crystal growth by VGF. Heeger Materials supplies pyrolytic boron nitride(PBN) VGF crucibles with high quality and at a competitive price.
Pyrolytic Boron Nitride (PBN) is a kind of advanced ceramic, that can be produced with 99.999% purity in high density. It is made by ammonia and Boron halide through a Chemical Vapor deposition(CVD) process in high temperature and high vacuum conditions: NH3 +BX3=BN+3HX, it can be produced as PBN plates and also can be produced as PBN final products directly like crucible, boat, coating, etc.
Pyrolytic Boron Nitride (PBN) VGF Crucible Feature
- High Purity (99.999%)
- No wetting with melted metal
- Thermal conductivity is controllable, improving the rate of yield
- Excellent thermal shock resistance
- Easy cleaning and Reusability
- Inert, no reaction with acid and alkali
