| Questions And Answer | Back Directory | [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.
