Hello,
Please see the figure below of the print screen of the data received for impedance spectroscopy.
How shall I proceed ahead to find out resistance and ionic conductivity from the data ? What other details can I obtain from the data ?
@Artur Braun..thank you for your answer. I will plot it. What info shall i provide for more explanation ? I have data for different temperatures.
I have performed impedance spectroscopy of ceramic pellet coated with platinum as electrodes at different temperature ( room temp to 650 C) with mentioned frequency range.
dear @bhasker soni,
You already have data for different temperatures for your impedance spectroscopy analysis. You can plot temperature dependence graph, then you can explore more about your system. ie: activation energy, dielectric study, conduction mechanism and etc.. you can refer to my publications for more information. Here some suggested papers for you
1.Investigation of the Ionic Conduction Mechanism in Carboxymethyl Cellulose/Chitosan Biopolymer Blend Electrolyte Impregnated with Ammonium Nitrate
2.Biopolymer Electrolyte Based on Derivatives of Cellulose from Kenaf Bast Fiber
3.Conductivity and Dielectric Behavior Studies of Carboxymethyl Cellulose from Kenaf Bast Fiber Incorporated with Ammonium Acetate-BMATFSI Biopolymer Electrolytes
After you plot the cole-cole plot (the relation between imaginary impedance and real impedance) you can determine the equivalent circuit from this book. the resistance is the value of the real impedance at zero frequency, which means that the imaginary impedance equal zero and the ionic conductivity measured from the relation induced in this paper

you have frequency, Z' and Z''. you can plot nyquist plot (Z' vs. Z''). the intercept of the low frequency on the x axis gives bulk resistance value, using this you calculate the conductivity.
also you can make bode plot (log freq vs. log Z' or Z''). fit the data using z-view and calculate the capacitance values.
Which formula is use for plotting between Z'' and Z' impedance to find ionic conductivity.
From LCR reading, we can easily find the value of resistance and by using R, l nd A (pellet measurements), we can easily calculate the value of conductivity from the following formula:
conductivity = (1/R). (l/A)
