Abstract

Investigation on the dielectric properties of CaCu₃Ti _4+xO_12+2x was carried out when x was altered in the range from -0.5 to 0.5. For x= -0.5, it was found through XRD that besides primary CCTO phase, there are also CuO and CaTiO₃ phases. For x= 0.5, additional TiO₂ was found besides dominating CCTO phase. When x increases from -0.5 to 0.5, it was found that dielectric constant decreases, varistor voltage and non-linear coefficient increase while the dielelctric loss decreases. According to IBLC theory, it is suggested that the change of the grain boundary structure results in different barrier height and surface state when x changes.
