potassium titanate

The electrochemical properties of a ceramic composite material in which a hollandite-like potassiumchromium titanate solid solution is presented as the main phase were studied using impedance spectroscopy. The dependences of the conductivity of the obtained composites on temperature in the range from 250 to 800°C were studied. The activation energies of volumetric, intergranular and grain volume conductivity were determined. The phase composition of the material and the crystallographic structures of individual phases were also established. 

The electrochemical and electrophysical properties of basic and protonated potassium titanates in contact with the graphite electrodes were studied using the method of impedance spectroscopy. The characteristics of potassium titanates are given depending on the methods of modification and on the methods of their processing. The activation energies for some compositions were determined.

The electrochemical and electrophysical properties of the protonated and modified with silver iodide potassium titanates, which can be applied in energy storage units, have been investigated by impedance spectroscopy. It has been shown that the dielectric losses at medium and high frequencies are weakly dependent on the polarizing voltage. It has also been established that transfer in modified potassium titanate can be made through potassium and silver ions.
