Abstract

The features of electrokinetic properties of suspensions of nano- and micro-sized Ce0.8Sm0.2O1.9 (SDC) particles obtained by laser evaporation and condensation (LIC) and solution combustion methods are presented. The influence of surface nitro groups in the composition of LIC nanoparticles on suspension stabilization and zeta potential value was revealed. The influence of updating the dispersion medium on the properties of suspensions was studied, as well as the addition of cerium nitrate on the electrokinetic properties of suspensions of nano- and micro-sized particles and the character of electrophoretic deposition. The irreversible nature of the loss of stability of the suspension of LIC nanoparticles was established. The influence of the porous character of microsized particles on the electrophoresis process was shown.
