Abstract
The effect of the bond valence on microwave dielectric properties of (1-x)CaTiO 3-x Li 1/2 Sm 1/2 TiO 3 ccramics was investigated in the range of 0.0 ≤ x ≤ 1.0. A complete solid solutions was formed with the orthorhombic perovskite structure in the entire composition range. As the Li 1/2 Sm 1/2 TiO 3 content increased, the deviation of the observed dielectric polarizabilities calculated by the Clausius-Mosotti equation from the theoretical values, calculated by the additivity rule of dielectric polarizahility, decreased with increasing bond valence of the B-site in ABO 3 perovskite compound. The temperature coefficient of the resonant frequency (TCF) of the specimens decreased, depending on the B-site bond valence in the tilted region (t < 1). Typically, the dielectric constant K= 114, Q.f = 3700 GHz, and TCF = 11.5 ppm/C for the x = 0.7 composition sintered at 1300 C for 3 h.
