【 摘 要 】

The behaviour of short - circuit currents in specimens of the polar cuts of lanthanum-gallium tantalate crystals with identical deposited electrodes before and after preliminary polarization is investigated. The temperature dependences of short - circuit currents in the temperature range 200-600 °C were measured. These currents are caused by the electrochemical processes on opposite polar cuts surfaces taking place at the crystal /electrode boundary.
