Product Description
Cerium hexaboride (CeB6) is a cathode material with extremely high electron emissivity due to its lower work function. It is more resistant to carbon pollution and has a longer life span than lanthanum boride cathodes. It is widely used in electron microscopes, microwave tubes, and electronics. Beam etching, electron beam welding, X-ray tube and free electron laser and other fields.
 rare earth hexaboride powder can be customized: lanthanum hexaboride, cerium hexaboride, praseodymium hexaboride, neodymium hexaboride, samarium hexaboride, europium hexaboride, dysprosium hexaboride, yttrium hexaboride, hexaboride Ytterbium, gadolinium hexaboride.
Product Features
