Effect of Heat Treatment on the DC Conductivity and Activity Energy of Li₂O-Fe₂O₃-P₂O₅ Glasses

Abstract:

Iron phosphate glasses with composition of 20Li2O-32Fe2O3-48P2O5 (in mol%) was prepared by melting, crushing and heat-treating process and the electrical properties were examined. It was found that the sample heat-treated at a temperature close to the glass transition temperature exhibit the maximum conductivity and the lowest activation energy, implying that heat-treatment may play an important role in the electrical properties of the glasses.
