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.

► Electric properties of alkaline and alkaline-earth borate in the melt — a crystal.
► Existence of a strong variation of conductivity depending on the concentration ions.
► Rapid growth of crystals results in a sharp growth of conductivity.
► These feature metaborates due to the exothermic transformation (crystallization).
