Attached figure is the EIS of LSGM electrolyte at different processing temperature.
Kindly guide me how to measure the Grain and grain boundary conductivity of this electrolyte ?
I shall be very thankful to you.
Regards.
Dear M Bilal Hanif,
You can calculate the grain and grain boundary conductivity using ZVIEW software. From the figure, I can see that you have two semicircles. Fit the circles using the equivalent circuit model, you will end with different R and CPE values for each semicircle. Calculate the capacitance using the obtained CPE. Depending upon the C values, the contribution of Grain, grain boundary, and the electrode can be detected. For example, the capacitance of grain should be in the range of 10^(-14)-10^(-10); grain boundary (10^(-10)-10^(-8), and electrode in the range of 10^(-6). After assigning the contribution to grain and grain boundary, you can calculate the conductivity using the resistivity obtained from the respective semicircles and dimensions of your sample.
I Hope, this answer helps you. Feel free to ask if u have any queries.
