Features of 99.5% Pure LaB6 Lanthanum Hexaboride Tube
1. Electron Emission Performance: Low work function and high emission current density; capable of stable electron emission at high temperatures, outperforming oxide and pure metal cathodes.
2. Thermal Stability: High melting point and low thermal expansion coefficient; low evaporation rate in a vacuum environment and long service life.
3. Poisoning Resistance: As surface lanthanum atoms evaporate, internal lanthanum atoms automatically replenish the surface, ensuring the emitting surface remains active.
Applications of 99.5% Pure LaB6 Lanthanum Hexaboride Tube
1. Electron Microscopes: Serve as a cathode material to provide high-brightness, stable electron beams.
2. Plasma Equipment: Utilized as an emission source due to its high melting point and thermal stability.
3. Electron Beam Equipment: Used in instruments requiring high-brightness electron beams, such as mass spectrometers, X-ray equipment, and traveling-wave tubes.
4. Vacuum Electron Tubes: Provide long-lasting, stable electron emission.
