Activation energies for the electrical conductivity of riebeckite. Conductivity (σ|| and σ⊥) data as a function of temperature plotted in Arrhenius space. The values for the activation energy for “pure” polaronic (T’,T’’) and polaronic plus H+-diffusion conductivity (T’’,700 K) are indicated. The activation energy derived from σ||(T) data in the entire temperature range (300–720 K) is 0.42 ± 0.01 eV. Error bars are smaller than the symbol size.
