N2 - High-dielectric-constant and low-loss ceramics in the (1-x)Ca 4MgNb2TiO12-xCaTiO3 system have been prepared by the conventional solid-state route. The forming of complete (1-x)Ca4MgNb2TiO12-xCaTiO3 solid solutions were confirmed by the X-ray diffraction pattern analysis and the measured lattice parameters, which linearly varied from a=5.5478 Å, b=7.7710 Å, and c=5.4543 Å for x=0.1 to a=5.4718 Å, b=7.6799 Å, and c=5.4262 Å for x=0.9. By increasing x, not only could the τf of the ceramics be turned to a near-zero value (∼-6.9 ppm/°C) at x=0.3, a substantial Q×f (∼20 200 GHz) and εr (∼43.88) could also be achieved simultaneously.
