Abstract :
Electrical property of lithium niobate crystals with various compositions from congruent to stoichiometric and Mg-doped and different crystal orientations are analyzed in the temperature range from 400 °C to 800 °C. The conductivity is found to decrease with increasinglithium concentration, and has little connections with the crystal orientations and Mg-doped. In addition, the activation energy of these lithium niobate related crystals are calculated based on the resistivities which have been linear fitted, and the mechanism of action work on the conductivity of lithium niobate and its related crystals at high temperature are analyzed.
