The anomalous resistivity‐temperature characteristics found in semiconducting barium titanates were studied in relation to their composition. The resistivity and impedance characteristics and the crystal structures were investigated for different compositions in the systems (Ba, ‐Sr) (Ti, Sn)O 3 , (Ba, Ca, Sr)TiO 3 ) (Ba, Pb)TiO 3 , Ba‐(Ti, Zr)O 3 , and Ba(Ti, Si)O 3 doped with 0.1 mole % of Ce and also in the system (Ba, Mg, Ce) TiO 3 . Bodies whose compositions were quite different from BaTiO 3 could not be semiconducting. The resistivity anomaly in each semiconducting body showed a good correlation with the crystal transition.
