Understanding the microwave dielectric properties of (Pb0.45Ca0.55)[Fe0.5(Nb1−xTax)0.5]O3 ceramics via the bond valence

The microwave dielectric properties of the (Pb0.45Ca0.55)[Fe0.5(Nb1-xTax)0.5]O3 ceramics were investigated in the range of x = 0.0-1.0. With increasing Ta2O5, the dielectric constant and temperature coefficient of resonant frequency (TCF) decreased, while the Q factor of the specimens increased. The...
