Solid electrolytes based on {1 − (x + y)}ZrO2-(x)MgO-(y)CaO ternary system: Preparation, characterization, ionic conductivity, and dielectric properties
Different composition of composite material of zirconium dioxide co-doped with magnesium oxide [MgO(x)] and calcium oxide [CaO(y)] according to the general molecular formula {1 − (x + y)}ZrO2-(x)MgO-(y)CaO were prepared by co-precipitation method and characterized by different techniques, such as XR...
