Synthesis of Nanostructured LaB6 Powders

Abstract

Nanocrystalline powders of LaB6 with an average crystallite size of 20 nm, as determined from x-ray diffraction analysis, have been obtained using a combustion synthesis technique that makes use of lanthanum nitrate, boron, and carbohydrazide as precursors. The optimum fuel-to-oxidizer ratio was found to be 0.25, which is quite low compared to typical combustion synthesis experiments. The powders are phase-pure except for about a 3 mol% contamination of LaBO3.
