The ceramic system of (1−x) Li3NbO4−x Ca0.8Sr0.2TiO3 prepared by solid reaction route has been found to possess excellent dielectric properties. Li3NbO4 was combined with Ca0.8Sr0.2TiO3 to obtain a two-phase ceramic system and to achieve a thermally stable material. As x value varied from 0.1 to 0.4, the temperature coefficient of resonate frequency values (τf) ranged from +119.1 ppm/°C to −30.7 ppm/°C...
