LiTaO3 is an important optical material. It may also be possible to use this material as a solid electrolyte for lithium-ion batteries which may be applicable in thin film solid-state batteries. Generally, ceramics have a wide range of impedances. Many ceramics have mixed charged species consisting of electronic as well as ionic charge carriers. This work investigates the conductivity of LiTaO3 materials using ac impedance spectroscopy technique measured as a function of temperature.
