Ionic Transport and Electrical Relaxation in Glass. Proposal for Renewal of USDOE Contract No. DE-AS05-78ER05781, 1 April 1982-31 Jul 1982

摘要

Precise electrical conductivity measurements have been carried out over a wide temperature range (-11 to 300 exp 0 C) on a set of six glasses of molar composition 0.25 (XNA sub 2 O + (1-X)K sub 2 O) -0.05 Al sub 2 O sub 3 - 0.70 SiO with X in the range 0.95 to 1, in order to verify a weak electrolye model of alkali ion conductivity. Results indicate that the percentage of mobile Na exp + ions in the single alkali glass varies from about 1% at -10 exp 0 C to 5% at 300 exp 0 C, results fairly similar to those obtained for a 0.25 K sub 2 O - 0.75 SiO sub 2 glass.
