Buy Nextgen Lanthanum Hexaboride Powder which is of high quality directly with low price. 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.
