ac- and dc-conductivity

The nature conductivity in the amorphous potassium polytitanate

The work is devoted to investigation of the anisotropy of conductivity and determination of the most likely charge carriers in the amorphous polytitanate potassium. Defined ac – and dc-conductivity, dielectric permittivity, dielectric loss tangent in mutually perpendicular directions compacted potassium polytitanate.
An increase in the shift of the peak and the dielectric loss tangent in a frequency region when measured along the preferred direction location lamellae potassium polytitanate.

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.-
