Mordenites containing tin(IV) oxide were prepared by heating the mordenites with tin(IV) sulfate or tin(II) chloride dihydrate. The conductivities were measured in atmospheres having various water partial pressures. The conductivities of the tin(IV) oxide containing mordenites were higher than the conductivity of the pure mordenite. The highest conductivity was 2.5 x 10−2S/cm, measured at 100C in an atmosphere with relative humidity of 100%.
