Dielectric Enhancement

Barium titanate (BT) - potassium niobate (KN) nano-structured ceramics with an artificial morphotropic phase boundary (MPB) structure were prepared by a solvothermal method at temperatures below 230 °C. Various characterizations of the BT-KN nano-structured ceramics revealed that the BT/KN molar ratio was 1, the porosity was around 30 %, and the interface between BT particles and KN crystals was heteroepitaxial. The apparent piezoelectric constant d33* was 136 pC/N, which was three times larger than that of 0.5BT-0.5KN dense composite ceramics. The concept proposed in this study can be useful to create piezoelectric ceramics with artificial MPB regions.

Alternating Voltage

Barium titanate and quartz mixed in different proportions were used to create porous piezoelectric ceramics. Three different sintering temperatures were used for the ceramics preparation; a nichrome wire was used as internal electrode in porous ceramics. Characteristics as porous area, porosity, and its relationship with quartz percentage and sintering temperatures were studied. Porous ceramics with an implanted electrode were created, by applying an alternating voltage in the internal electrode that controlled the liquid permeability coefficient, calculated by the Darcy Law.
