Cerium Hexaboride Powder

Edgetech Industries, Advanced Ceramics Division supplies high-quality and competitive price advanced Cerium Hexaboride (CeB6) Powder.


Cerium Hexaboride Powder, (CeB6) Powder


Cerium Boride, also called Cerium Hexaboride or CeB6, is a refractory ceramic material. The principal use of cerium hexaboride is a coating of hot cathodes, or hot cathodes made of cerium hexaboride crystals. It usually operates at temperature of 1450 °C. Cerium Hexaboride Powder is the raw material for CeB6 ceramics and deposition materials.

Edgetech Industries provides CeB6 with 99.5% purity, the particle size range is from -20 mesh to -500 mesh. The particle size and the purity also can be customized.

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 vacuum.

-Used to coat some high-current hot cathodes

-Electron microscopes such as SEM, TEM

-X-ray tubes

-Electron lithography

-Electron beam welding


Packing of Cerium Hexaboride (CeB6)


CeB6 powder should be stored in dry, cool and sealing of the environment, cannot be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.

Our Cerium Hexaboride Powder is carefully handled to minimize damage during storage and transportation and to preserve the quality of products in their original condition.
