Nanosize precursors with controlled dispersity were synthesized using the reverse co- precipitation sol-gel method by varying the concentrations of the initial salt solutions. A set of final ceramics (0.08Y 2 O 3 -0.92ZrO 2 , 0.09Ce 2 O 3 -0.91ZrO 2 , 0.06Ce 2 O 3 -0.06Y 2 O 3 -0.88ZrO 2 , mol.%) was produced from the precursor powders of different dispersity; their conductivity and sensor properties were investigated. As a result, 0.08Y 2 O 3 -0.92ZrO 2 ceramics manufactured from the precursor powders with the average agglomerate size of 100-140 nm was shown to be the optimal choice for the use as a solid electrolyte with anionic conductivity.
