Resumo

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.
