Temperature dependences for conductivity of an Algerian montmorillonite was studied in
comparison with various ion exchanges. By using conductivity measurements, activation
energies for ion transport were determined. The obtained values for conductivity and
activation energy are similar to those of some protonic conductors. Electrical parameters
were extracted from impedance spectra and correlated to the water content (from
Thermogravimetric Analysis results, TGA) and to dehydration energy (from Differential …
