Pyrolytic Boron Nitride (PBN) LEC Crucible

The Pyrolytic Boron Nitride (PBN) LEC Crucible, with its superior thermal conductivity and expansion coefficients, ensures a stable temperature gradient essential for the Liquid Encapsulated Czochralski (LEC) technique. LEC employs a liquid covering agent to seal the melt and control volatilization for crystal growth, with the LEC Crucible serving as the vessel for this process.

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.

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) LEC Crucible Applications

• GaAs Crystal Growth: Provides a chemically stable and corrosion-resistant container for growing high-quality gallium arsenide using the LEC method.
