CeBix, LaB6 and Tungsten Filaments

Overview & Advantages:

For years, LaB6 has been the industry standard thermionic emission cathode material. CeBix™ (cerium hexaboride), that can be used as a direct replacement for LaB6. CeBix™ has several advantages over LaB6 cathodes, including:

  • Longer Lifetime
  • Faster Start-up
  • Lower Work Function
  • Higher Brightness
  • Lower Evaporation Rate
  • Capability to Recover from Contaminates
  • Reduced Effects of O2
  • Faster Stabilization after Air Exposure
  • Lower Temperature Operation at the Optimum Filament Setting

CeBix™ cathodes are a simple, direct replacement for LaB6 cathodes in nearly every instrument currently using LaB6.
