Abstract: 

Experimental studies of the electrochemical and electrophysical properties of protonated potassium polytitanate and sodium-modified pryderite were carried out using the method of nonlinear impedance spectroscopy. The frequency dependencies of the resistance of the volume of grains and grain boundaries were determined depending on the magnitude of the polarization voltage (DC) and on the value of the perturbation signal (AC).

Key words: 
protonated potassium polytitanate
nonlinear impedancemetry
