Superior dielectric and varistor properties of ZnO or SnO2 diffused calcium copper titanate ceramics

Sub-micrometer-sized (0.33 μm) polycrystalline powders of calcium copper titanate (CCTO) were synthesized via the solgel method. Compacted calcined powders were sintered at 900 °C/2h to obtain porous (95% density) ceramics. X-ray structural investigations revealed the presence of ZnO or SnO2 traces...
