The complex conductivity of lithium aluminosilicate based glasses and glass-ceramics (Zerodur from Schott) has been investigated in a broad range of temperatures (200 K < T < 700 K) and frequencies (10 mHz<v<2.5 THz). The data are presented in terms of the conductivity and the electrical modulus formalisms. The width of the modulus loss peak as measured for the ceramic sample is broader than that determined for its precursor glass. This result is shown to be associated with the considerably smaller dc conductivity of this material.

AbstractThe glass-ceramics of the phosphorus containing Na5RSi4O12type (R=rare earth) Na+-superionic conductors (Narpsio-V) in the system Na2O-Sm2O3-P2O5-SiO2 were prepared by crystallization of glasses with the composition Na3+3x-ySm1-xPySi3-yO9. The optimum conditions for crystallization were discussed with reference to the conduction properties and the preparation of uncracked bulky glass-ceramic Narpsio-V. The ionic conductivity of the glass-ceramic Na3.9Sm0.6P0.3Si2.7O9 at 300°C was drastically enhanced from 2.38×10-2 S/cm to 7.15×10-2 S/cm upon implantation of 200 keV Na+ ions to a fluence of 1 × 1015 cm-2.
