In general, the ceramics prepared were multiphase materials. However, single phase specimens having orthorhombic perovskite structure similar to CaTiO3 could be obtained in the vicinity of x=0.25. As Ti concentration increased, the dielectric constant (epsilon(r)) increased, the quality factor Q decreased and the temperature coefficient of resonant frequency (tau(f)) changed from negative to positive value. The temperature coefficient of resonant frequency of O ppm/degrees C was realized at x=0.05. The Q . f(0) value and epsilon(r) for this composition were found to be 27,800 GHz and 32.3, respectively.
