Experimental Investigations of the AC-Conductivity in NaTaO₃ Ceramic Materials Doped with Cu and Al Metal Ions

Two ceramic samples of sodium tantalate (NaTaO₃), doped with metal ions of copper (Cu; sample S1) or aluminum (Al; sample S2), were obtained by the sol-gel method. Complex impedance measurements in the frequency range (200 Hz–2 MHz) and at temperatures between 30 °C and 90 °C...
