• Uses: Lanthanum Boride is mainly made into Lanthanum Boride (LaB6) hot cathode which electronic source is used as electronic source for electron microscopy, electron-beam exposure machine. LaB6 is also used as a size/strain standard in X-ray powder diffraction to calibrate instrumental broadening of diffraction peaks. Lanthanum Boride powder can be further processed to various shapes of rods, tubes, discs and special designed form. Lanthanum boride is employed in hot cathodes, which enact and includes electron microscopes, microwave tubes, electron lithography, electron beam welding, X-ray tubes, and free electron lasers. It is administered as a size or strain standard in X-ray powder diffraction to calibrate instrumental broadening of diffraction peaks. It exercises as a superconductor. It has a great potential as a thermionic emitter in renewable energy applications. It is widely used in teleran, electronic industry, instrument, medical equipment, metallurgy and enviromental protection.
