| Abstract: | In our work single crystals of Mg4.5Na7(P2O7)4 were prepared, pulverized, pressed into pellets and sintered in order to measure the electrical conductivity of polycrystalline specimens. The conductivity was also measured on glassy specimens obtained by the melting of previously prepared crystals. The electrical conductivities at 25°C with values of the order of 10−16 Ω−1 cm−1 for polycrystalline samples and a value of the order of 10−14 Ω−1 cm−1 for glass, show that the glassy phase of Mg4.5Na7(P2 because of its greater molar volume and loosely packed structure, is a better matrix for ionic motion. |
