3N Purity Cerium Hexaboride (CeB₆) With Cathode Brightness Cas No.12008-02-5

Cerium Hexaboride (CeB₆) is an inorganic compound composed of cerium and boron, serving as a core high-performance material for thermionic cathodes. It is mainly used in thermionic cathode fabrication, either directly as bulk crystals or as a coating. It is often used together with LaB₆ in high-current thermionic cathode assemblies. CeB₆ is widely applied in high-end electronic devices and special processing fields, including electron microscopes, microwave tubes, electron beam lithography, electron beam welding, X-ray tubes, and free-electron lasers.
