Three solid solution phases in the SrO-CaO-CuO system, Sr2-xCaxCuO3 (0≤x≤2), Sr-2-1$/CaxCuO2 (0≤x<0.5) and Sr3-xCaxCu5Oy(0≤x≤1.8), were prepared at 1273 K under 0.1 MPa of oxygen. These phases showed semiconducting behavior below 300 K. The highest conductivity of 6.3×103 S·m-1 at 300 K measured for Sr3-xCaxCu5Oy (x=1.8).
