LEC Type PBN Crucible Description

Pyrolytic Boron Nitride (PBN) represents an advanced ceramic crafted from a high-density powder boasting 99.999% purity. The Pyrolytic Boron Nitride Crucible (LEC Type) is formed through a Chemical Vapor Deposition (CVD) process using BCl3 and NH3 under high-temperature, low-pressure conditions.

The Liquid Encapsulation Czochralski (LEC) method employs a liquid covering agent to seal the melt, controlling volatilization for crystal growth. The LEC Type Pyrolytic Boron Nitride Crucible serves as a vessel, facilitating crystal growth within the LEC process.
