Pyrolytic Boron Nitride Insulation Ring (PBN Insulation Ring) is a high-performance ceramic component prepared via the CVD process. Its core features include ultra-high purity (99.999%), excellent high-temperature stability (up to 2200 °C), strong chemical inertness, as well as superior thermal shock resistance and electrical insulation properties.
Applications:
Semiconductor Industry：Used in MBE, MOCVD, PVD, and other equipment as heating chamber components, electrode insulators, and structural parts inside reaction chambers, providing electrical insulation and thermal isolation.
Vacuum Coating Equipment：Serves as an insulating component for evaporation sources, ion sources, and target supports, preventing current leakage or short circuits at high temperatures.
Crystal Growth Equipment：Applied as insulating support rings in single-crystal growth furnaces for sapphire, silicon carbide (SiC), and gallium nitride (GaN), ensuring uniform thermal fields and stable equipment operation.
High-Temperature Experimental Equipment：Used as electrode spacers and insulating structures in heating systems for heat treatment furnaces and analytical instruments.
Industrial Electric Heating Systems：Employed in vacuum furnaces, graphite heaters, and tungsten-molybdenum electrode assemblies to enhance system insulation performance and extend service life.
