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.

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.
