Description of Cerium Hexaboride Ceramic Part

Cerium Hexaboride is a ceramic material wildly used in electron microscopes with a low work function making it one of the most known cathode materials for electron emissivity, and it is very stable in a vacuum. CeB6 has an evaporation rate at normal operating temperatures near 1800 K that is lower than that of LaB6.

Cerium Boride or (Cerium Hexaboride) is generally immediately available in most volumes. Borides are all hard, high-melting materials with metal-like conductivity. They are stable to nonoxidizing acids but break down in strong oxidizing agents and strong alkalis.

Applications of Cerium Hexaboride Ceramic Part

Used to coat some high-current hot cathodes
