Pyrolytic Boron Nitride Crucible (LEC Type) Description
Pyrolytic Boron Nitride Crucible (LEC Type) is a specialized container used in crystal growth processes, particularly in the production of high-purity single crystals. It is designed for use in the Liquid Encapsulated Czochralski (LEC) crystal growth technique. LEC is a crystal growth technique that involves melting a polycrystalline feed material in a crucible and slowly pulling a single crystal from the melt. The liquid encapsulation helps to control the crystal growth process and maintain a high level of purity.
PBN is a synthetic, high-purity form of boron nitride, which is a compound of boron and nitrogen. PBN exhibits excellent thermal and chemical stability, as well as high electrical resistivity. These properties make PBN suitable for applications in high-temperature and corrosive environments.
