Lanthanum boride (LaB6)-Powder

Characteristic

Lanthanum Boride, also called Lanthanum Hexaboride or LaB6, is an inorganic chemical and refractory ceramic material. It has a high melting point of 2210 °C and is insoluble in water and hydrochloric acid. It has a low work function and one of the highest electron emissivity known, and is stable in a vacuum. Therefore, the principal use of lanthanum hexaboride is as a coating deposited by physical vapor deposition of hot LaB6 filament, or to manufacture hot cathodes made of LaB6 single crystals. It is also used as a size/strain standard in X-ray powder diffraction to calibrate instrumental broadening of diffraction peaks.
