摘要: Mn-doped CaCu3Ti4O12 ceramics with nominal composition CaCu2.85Mn0.15Ti4O12 (CCMTO) have been prepared and their radio- micro-wave dielectric properties established. At 300 K, dense CCMTO appreciable grain resistivity, ∼20MΩcm, exhibit microwave resonance er∼93, Qf∼3950GHz (at 3.95GHz) temperature coefficient of resonant frequency ∼+657ppm∕K. er decreases smoothly from ∼150 to 90 in the range 10–300K, obeys Curie-Weiss law ∼60–180K, is consistent incipient ferroelectricity. The source ferroelectricity potential applications are discussed.
