  • Cerium hexaboride cathodes have a lower evaporation rate at 1700 K than lanthanum hexaboride, but they become equal at temperatures above 1850 K. Cerium hexaboride cathodes have one and half the lifetime of lanthanum hexaboride, due to the former's higher resistance to carbon contamination. (wikipedia.org)
  • Lanthanum hexaboride and cerium hexaboride are widely used in electron gun and other fields as high electron emissivity products. (ceravite.com)
  • Hexaboride cathodes are about ten times "brighter" than tungsten cathodes, and have 10-15 times longer lifetime. (wikipedia.org)
  • Devices and techniques in which hexaboride cathodes are used include electron microscopes, microwave tubes, electron lithography, electron beam welding, X-ray tubes, free electron lasers and several types of electric propulsion technologies. (wikipedia.org)
