摘要: Abstract In this work, the influence of Lu 2 O 3 doped on dielectric and electrical properties CaCu Ti 4 12 was reported. -doped CCTO prepared by a conventional solid state technique using CuO, TiO , CaCO as starting materials. The samples were studied X-ray diffraction (XRD) scanning electron microscopy (SEM); measurements measured in 10  Hz–10 7  Hz frequency range at room temperature; nonlinear behavior all measured. doping resulted an increase constant CCTO, but decreased stability dependence. Increasing concentrations decreasing coefficients.
