Novel electrolytes based on complex tungstates with general formula Cs R Ti 0.5 (WO 4 ) 3 ( R = Al, Cr) were investigated. X-ray diffraction results show that the single-phase samples can be formed by ceramic technology at 1023 K. Dielectric measurement results indicate that the conductivity of CsCrTi 0.5 (WO 4 ) 3 can reach 0.0011 S cm −1 at 1023 K. The activation energy of the compound calculated according to the Arrhenius plots are 0.4-0.6 eV for T > 873 K. Impedance spectra of the ceramic samples at different temperatures are characterized the high frequency semicircle and a straight line at low frequencies, which is typical for ion-conducting materials. Cs R Ti 0.5 (WO 4 ) 3 ( R = Al, Cr) ceramic materials correspond to a new strategy to design novel electrolytes for various applications.
