· JVASP-26822· RbNaTiO3

RbNaTiO3 is a mixed-cation perovskite ceramic compound containing rubidium, sodium, and titanium oxides. This material belongs to the ferroelectric and piezoelectric ceramic family and is primarily investigated in research contexts for its potential electromechanical and dielectric properties. The dual alkali-metal composition (Rb and Na) offers tunable ferroelectric behavior compared to single-cation perovskites, making it of interest for applications requiring controlled polarization response and mechanical coupling.
