The electrical conductivity of albite was in-situ measured at pressures of 1.0, 2.0 GPa and temperatures of 673-973 K using a.c. impedance spectroscopy method in YJ-3000t multi-anvil press. The experimental results indicate that the electrical conductivity (σ) of albite ranges from 10-3.0 to 10-5.5 S/m. The modulus and phase angle of complex impedance strongly depend on frequency. The electrical conductivity of samples rapidly increases with increasing temperature (T), and the relationship between lg σ and T-1 fits Arrhenius relation. In addition, the electrical conductivity of samples decreases with increasing pressure in the investigated temperature and pressure range. The dominating conduction mechanism for albite is suggested to be the migration of sodium cations within the channels in the aluminosilicate framework.
