This study presents a methodology for the fabrication and investigation of the electrical capacitance properties of zirconium dioxide (ZrO2)-based nanopowders doped with 3 mol.% yttrium oxide (Y2 O3). The main focus is on the creation of dense compacts using high hydrostatic pressure up to 500 MPa, as well as the optimization of the technique for applying electrical contacts to ensure measurement stability. The experimental section describes a setup that enables the recording of discharge characteristics of the samples in a temperature range from 3to 400 °C. The article provides data on the dependence of capacitance on circuit resistance and applied voltageas well as the influence of thermal treatment – specifically annealing at 400 °C and 500 °C – on structural ancapacitive parameters. It is demonstrated that under optimal conditions – namely, a voltage of 10 V, a resistancof 10 kΩ, and air humidity of 50% – a maximum capacitance of up to 1256.948 µF is achieved. The study alsshows that increasing the annealing temperature improves the capacitive properties, which is attributed to changein the material’s microstructure. The presented results highlight the potential of YSZ nanopowders in developinsolid-state nanoionic energy storage devices with high energy density, making them promising candidates for use ienergy storage systems and microelectronics.
