N1 - This research was funded by the Russian Science Foundation, grant number 18-13-00355. The electron microscope of the Ural Center for Shared Use “Modern nanotechnology” Ural Federal University (Reg. No. 2968) was used with financial support of Ministry of Science and Higher Education of the RF (Project No. 075-15-2021-677). The laser ablation equipment of the Center for Shared Use “Electrophysics” in the Institute of Electrophysics, Ural Branch of Russian Academy of Sciences was used with financial support of Ministry of Science and Higher Education of the RF (No. 122011200363-9).

N2 - In the present work, a study was carried out to investigate the key factors that determine the uniformity, mass, thickness, and density of compacts obtained from nanopowders of solid solutions of yttrium and lanthanum oxides ((LaxY1−x)2O3) with the help of the electrophoretic deposition (EPD). Nanopowders were obtained by laser ablation of a mixture of powders of yttrium oxide and lanthanum oxide in air. The implemented mechanisms of the EPD and factors of stability of alcohol suspensions are analyzed. It has been shown that acetylacetone with a concentration of 1 mg/m2 can be used as a dispersant for stabilization of isopropanol suspensions of the nanoparticles during the EPD. It was shown that the maximum density of dry compacts with a thickness of 2.4 mm reaches 37% of theoretical when EPD is performed in vertical direction from a suspension of nanopowders with addition of acetylacetone. © 2022 by the authors.
