Nano lanthanum hexaboride has diverse uses in traditional & high-tech industries like mechanics, electronics, aeronautics, metallurgy, chemistry, environment, etc.
Based on electron emission lanthanum hexaboride has a low work function that is probably even lower for selected crystal planes. But lanthanum hexaboride also retains adsorbed cesium well and reaches optimum cesiated surface potentials considerably below those attained by the most effective metals, those with high bare work functions. And

The large gain in brightness and long operating life of Lanthanum Hexaboride cathodes are well known. Kimball Physics' LaB 6 cathodes are at least equal in these respects to other cathodes and they also offer a price advantage. Additionally, Kimball designed their cathodes with a much larger crystal and a one-piece base.

** The z-ratio is unknown. Therefore, we recommend using 1.00 or an experimentally determined value. Material Notes "Indium" Bonding is recommended for these materials. Many materials have characteristics which are not amenable to sputtering, such as, brittleness and low thermal conductivity.
The number of electrons in each of lanthanum's shells is [2, 8, 18, 18, 9, 2] and its electron configuration is [Xe] 5d 1 6s 2. The lanthanum atom has a radius of 187 pm and a Van der Waals radius of 240 pm. Lanthanum was first discovered by Carl Mosander in 1838. In its elemental form, lanthanum has a silvery white appearance.
Lanthanum hexaboride (LaB6) nanocrystals, with an ∼1000 nm wavelength localized surface plasmon resonance ideal for interacting with solar near-infrared radiation, have been synthesized for the first time in a relatively low temperature flask reaction using sodium borohydride as both boron source and "solvent".
