摘要：
The DC electrical conductivity of Li2O-K2O-Fe 2O3-B2 O3 glasses is analyzed. The conduction process in borate glasses containing iron oxide was found to be polaronic in nature. It was observed that the DC conductivity of these glasses was of ionic origin and the absence of polaronic conduction was due to sufficient concentration of positive lithium ions. It was found that density and molar volume of the glasses changed with the composition.
