Dielectric Properties in LiTaO₃-CaTiO₃ Solid Solution Ceramics

抄録

A set of solid solution ceramic synthesizing in (1-x) LiTaO₃-xCaTiO₃, O≤x≤0.2, family made it clear that CaTiO₃ component lowered their Curie temperature at 16°C/mol% up to 17%, where the solution effects were markedly changed. The more the CaTiO₃ concentration came, the more significant the feature of the relaxer like phase transition was. The reciprocal dielectric permittivity depended upon uniaxial pressure, showing their possibility of application for pressure sensors.
