Abstract: La_0.8Sr_0.2CrO₃-ITO thermocouples were successfully fabricated by screen printing. The La_0.8Sr_0.2CrO₃ powder used for screen printing was obtained by the sol-gel method. The highest thermal voltage output was maintained at 270 mV at 1270°C. The microstructure of La_0.8Sr_0.2CrO₃ and ITO electrode films were analysed by SEM. Thermoelectric response test was implemented to measure the performance of La_0.8Sr_0.2CrO₃-ITO thermocouple by three times of thermal cycles. The results indicated that La_0.8Sr_0.2CrO₃-ITO thermocouple showed good stability at high temperature.
