More info
Pyrolytic Boron Nitride (PBN) VGF Crucible serves as the ideal vessel for single-crystal growth. VGF is the primary technology worldwide for growing GaAs and InP compound semiconductor single crystals.
Pyrolytic Boron Nitride (PBN) is an advanced ceramic with up to 99.999% purity and high density, produced via Chemical Vapor Deposition (CVD) using ammonia and Boron halide in high-temperature, high-vacuum conditions (NH3 + BX3 = BN + 3HX). It can be manufactured as plates or directly as final products like crucibles, boats, and coatings.
HM is a leading supplier of high-quality Pyrolytic Boron Nitride (PBN) products, including PBN rings, PBN plates/sheets/discs, PBN crucibles (OLED, MBE, VGF, LEC), PBN rods, PBN heaters, and PBN coatings.
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
