Abstract

We present a general rule for the perovskite oxide ceramics: "A large piezoelectric constant in AB O3 perovskite ceramics can be obtained by tuning the weight ratio of A and B sites, W_A/W_B or W _B/W_A to 3. Piezoelectric constant decreases significantly when W_A/W_B or W_B/W_A is in the range of 0.5-2.0, termed as forbidden zone." A comparative analysis was conducted for broad range of materials demonstrating the applicability of proposed rule. Further based on this rule optimized compositions in BaTiO3 and alkali niobate based systems were developed. Polycrystalline ceramics in modified BaTiO3 system were found to exhibit longitudinal piezoelectric coefficient (d33) of 330 pC/N, while alkali niobate ceramics showed d33 of 294 pC/N.
