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.
