Calcium Sulfate, Solid Electrolyte, Impedance Spectroscopy Method, Ionic ConductivityAbstract
This paper presents the results of a study of the electrical properties of a microstructurally heterogeneous composite material consisting of a calcium sulfate, phosphoric acid, and carbon system. The electrical conductivity and conductivity mechanism of the material samples at room temperature were studied. The material’s electrical conductivity was found to be quite high and typical of solid electrolytes.
