A solid-state reaction route to prepare LaB6 nanocrystals in vacuum
Source abstract
Abstract
Abstract LaB 6 nanoparticles were successfully synthesized at 1200 °C via a solid-state reaction. The synthesis was carried out under vacuum condition, with LaCl 3 and NaBH 4 as the reactants. XRD (X-ray diffraction) patterns indicated the formation of LaB 6 . Result from FESEM (field emission scanning electron microscope) showed that the products were mostly composed of cubic particles with sizes ranging from 20 nm to 100 nm. HRTEM (high-resolution transmission electron microscope) images confirmed the formation of nanocrystalline LaB 6 with dominant (1 0 0) planes. Effects of different processing parameters during the reaction were investigated as well.
