Abstract: This study investigates the thermoelectric properties of Ca2Fe2O5 over a temperature range of 7˚C to 50˚C. The experiment measured the voltage generated by temperature differences across two sides of the material, with a focus on the voltage response at temperatures both below and above room temperature. Results indicate that at lower temperatures (7˚C to 15˚C), the voltage generated by the temperature difference was higher, though not directly proportional to the magnitude of the temperature gradient. The highest voltage recorded for the smallest temperature difference in this range was 109 mV, observed between 14.6˚C and 17.6˚C (smallest temperature difference, 3˚C). Similarly, at temperatures above room temperature, the voltage generated was relatively lower, peaking at 125 mV between 9˚C and 44˚C (higher temperature difference). These results suggest complex behavior of Ca2Fe2O5’s thermoelectric response, with non-linear relationships between voltage and temperature differences at both low and high temperatures.
