Impedance spectroscopy potassium polytitanate, modified sulfate cobalt (II). High temperatures
The behavior of the conductivity and of electrophysical characteristics of potassium polytitanate modified by cobalt (II) sulphate was investigated under the temperature from 100 to 800 °C. The temperature dependence of AC and DC-conductivity was found, activation energy was appreciated in the low and high temperature phases. A equivalent circuit describing the transport processes in the studied composite based on potassium polytitanate was proposed.-
