A relation between absorption band frequencies connected with free carrier absorption the IR‐region, mobility values, and phase transition temperatures in titanates, tantalates, and niobates is discovered. The existence of a single mechanism determining both phase transition and carrier kinetics in the conduction band is supposed.
