Dielectric properties of CaCu3Ti4O12 based multiphased ceramics [PDF]
, 2006 A “soft chemistry” method, the coprecipitation, has been used to synthesize the perovskite CaCu3Ti4O12 (CCT). Three main types of materials were obtained for both powders and sintered ceramics: a monophased consisting of the pure CCT phase, a biphased ...
