Pyrolytic Boron Nitride (PBN) ceramic crucibles are specialized components used in various high-temperature applications, particularly in the growth of semiconductor crystals through methods like the Vertical Gradient Freeze (VGF) technique.
PBN is a synthetic, high-purity ceramic material composed of boron and nitrogen. It is produced through chemical vapor deposition (CVD) processes, resulting in a highly pure and dense material. PBN crucibles are often used in the VGF crystal growth technique, where a single crystal is grown from a molten material in a controlled thermal environment.
