Pyrolytic Boron Nitride (PBN) VGF Crucible

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.

Types of Pyrolytic Boron Nitride (PBN) Crucibles 

OLED PBN Crucibles
As the name suggests, these PBN crucibles are used for OLED evaporation processes. They perform reliably at high temperatures, offer strong chemical inertness, and are well known for their thermal stability.
MBE PBN Crucibles
MBE crucibles are designed for molecular beam epitaxy processes. With the inherent inertness and thermal stability of PBN, these crucibles help slow the release of gases during chemical reactions, ensuring a cleaner and more controlled environment.
VGF PBN Crucibles
These crucibles are used for synthesizing materials such as GaAs and Ge. VGF PBN crucibles withstand high temperatures and support controlled crystal growth, helping reduce structural defects and improve crystal uniformity.
LEC BN Crucibles
The growth of GaAs and InP often relies on the liquid-encapsulated Czochralski (LEC) method. PBN LEC crucibles offer stable chemical properties and strong corrosion resistance. They are not easily affected by encapsulating materials, ensuring the slow and steady extraction of high-quality single crystals.

Pyrolytic Boron Nitride (PBN) VGF Crucible Applications 

• GaAs Crystal Growth: Provides a stable, high-temperature container for producing high-purity gallium arsenide using the Vertical Gradient Freeze method.
• Germanium (Ge) Crystal Production: Supports controlled melting and solidification of Ge, improving crystal uniformity and reducing defects.
• III–V Semiconductor Fabrication: Used for growing advanced compound semiconductors needed in detectors, power electronics, and optoelectronic devices.
• High-Temperature Thermal Processing: Offers excellent insulation and chemical stability for processes requiring precise thermal gradients.
• Research & Development: Common in laboratory crystal growth experiments where purity, stability, and consistent thermal performance are critical.
