Measurement of electrical conductivity (s) and Seebeck coefficient (S) of the studied superionic system Li2O: P2O5: WO3 have been reported in the temperature range 415K to the melting point 1110K of the solid. All the measurement have been performed on solidified melt. The studied system shows a clear superionic phase. In the temperature range 950K to 1110K, it shows high ionic conductivity (si ~ 90W-1 m-1 at 1050K) with small (0.38eV) activation energy and almost negligible electronic conductivity. Molar magnetic susceptibility (XM) and dielectric constant (K) have also been measured against temperature to confirm anomalies observed in s and S results.
