Abstract
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 < nu < 2.5 THz). The data are presented in terms of the conductivity and t he electrical modulus formalisms. The width of the modulus loss peak a s measured for the ceramic sample is broader than that determined for its precursor glass. This result is shown to be associated with the co nsiderably smaller de conductivity of this material.
