Abstract:
The aim of this work is to synthesize new nanostructured copper-zinc lanthanum and alkaline metal
manganites. Polycrystalline copper-zinc manganites of lanthanum and alkali metals were synthesized by the
method of ceramic technology from lanthanum (III), copper (II), zinc (II), manganese (III) oxides, and lithium,
sodium, and potassium carbonates in the range of 800-1200 oC. Nanostructured particles were obtained by
grinding the synthesized polycrystalline compounds at the «MM301» vibration mill of «Retsch» (Germany). By
indexing X-ray images of nanostructured copper-zinc lanthanum and alkaline metal manganites, it was found that
they crystallize in cubic syngony. Their lattice parameters are determined. There is a pattern in the change of the
lattice parameters from the ionic radii of alkaline metals.
