摘要：

Both surface and bulk conductivity measurement have been simultaneously performed in NaCl single crystals cantaining Ca2+ of 10 ppm purity in the temperature range of 200-650 degrees C. The experimental results have been analyzed in terms of a double layer near the crystal surface. The formation energy of positive ion vacancy at the surface is found to be 0.57 eV.
