Cerium Hexaboride (CeB6) Ceramics

Cerium Hexaboride Description

Cerium Hexaboride ProducstCerium Boride, also called Cerium Hexaboride or CeB6, is a refractory ceramic material. It has a low work function and one of the highest electron emissivity known, and is stable in vacuum. Therefore,tThe principal use of cerium hexaboride is a coating of hot cathodes, or hot cathodes made of cerium hexaboride crystals. Cerium boride cathode usually operates at temperature of 1450 °C because it shows lower evaporation rate at 1427℃ than lanthanum boride, but it becomes equal at 1577℃ and higher above that.
