Lanthanum hexaboride LaB6 Powderis an inorganic chemical, a refractory ceramic material with a melting point 2210 °C and density 2.61g/cm3. It is insoluble in water and hydrochloric acid. It has a low work function and one of the highest electron emissivities known, and is stable in vacuum. Lanthanum hexaboride principal use: in hot cathodes, either as a single crystal or as a coating deposited by physical vapor deposition. LaB6 is also used as a size/strain standard in X-ray powder diffraction to calibrate instrumental broadening of diffraction peaks. LaB6 is a superconductor with a relatively low transition temperature of 0.45 K. --- in radar aerospace, in electronics industry, in environmental protection, polyethylene film sheet surface coating to keep out sunlight and infrared.
