Abstract
- An In<subscript>2</subscript>O<subscript>3</subscript>/ITO thin film thermocouple was prepared via screen printing. Glass additives were added to improve the sintering process and to increase the density of the In<subscript>2</subscript>O<subscript>3</subscript>/ITO films. The surface and cross-sectional images indicate that both the grain size and densification of the ITO and In<subscript>2</subscript>O<subscript>3</subscript> films increased with the increase in annealing time. The thermoelectric voltage of the In<subscript>2</subscript>O<subscript>3</subscript>/ITO thermocouple was 53.5 mV at 1270 °C at the hot junction. The average Seebeck coefficient of the thermocouple was calculated as 44.5 μV/°C. The drift rate of the In2O3/ITO thermocouple was 5.44 °C/h at a measuring time of 10 h at 1270 °C.
