Abstract
Modified CaTiO3 (CTO) ceramics were prepared by the conventional solid-state method. The samples belong to the Pbnm spatial group, showing an orthorhombic structure. The microwave dielectric properties of the Ca[(Li1/3Nb2/3)xTi1−x]O3−δ for ball-milled samples with ratio of 2.4 balls/g, which were calcinated at 900°C (during 5h) and sintered at 1000°C (during 3h) were investigated. The dielectric permittivity decreased with the decreasing of titanium amount. A decrease in the temperature coefficient in resonant frequency (τf) was observed with the increase of the X value.
