The role of nanostructures in the formation of the emission properties of oxide-nickel cathodes
The electronic and crystal structures of oxide-nickel compositions based on ternary barium-calcium-strontium carbonates containing nickel nanoparticles and nanocrystals of barium carbonate have been studied by electron spectroscopy and precision X-ray structural analysis. It was found that nickel nanoparticles have a significant effect on the parameters of the electronic structure of barium oxide crystallites formed in these compositions during their heat treatment. It is shown that X-ray diffraction analysis can be used as the basis for the method of quality control of ternary carbonates for their effective use in the composition of oxide-nickel cathodes.
