Ionic conductivity of alkaline (Li2O, Na2O) and alkaline-earth (BaO) borates in crystallization (vitrification) region

In this paper we report the existence of abnormal behavior of electric properties of alkaline (Li2O,Na2O) and alkaline-earth (BaO) borate in the melt—a crystal (glass) transition region. Results of measurement of conductivity in the mentioned interval evidence the existence of a strong variation of electric properties depending on the concentration of alkaline and alkaline-earth ions. The reasons of such behavior are discussed.
