چکیده انگلیسی
La1-xSrxCrO3-In2O3 thick film thermocouples were fabricated by screen-printing method for high temperature sensing and the effects of Sr2+ content were investigated systematically. All La1-xSrxCrO3 thick films showed well crystallization with orthorhombic unit cell. Their average particle sizes showed the tendency of first increase then decrease gradually with the increase of Sr2+ content, and the maximum of average particle size was 1.76â¯Î¼m. At the same time, the conductivities were improved with the increase of Sr2+ content. The thermoelectric properties of La1-xSrxCrO3 depended on the Sr2+ content and the average Seebeck coefficients had an exponential decay tendency with the increase of Sr2+ content. For La1-xSrxCrO3 (xâ¯=â¯0.1-0.4)-In2O3 thermocouples, excellent repeatability and stability were observed through multi-cycles and long-time usage testing at high temperature. The La0.7Sr0.3CrO3-In2O3 thick film thermocouple with excellent thermal stability (drift rate: 0.81â¯Â°C/h) and reliability makes it become a promising candidate high sensitivity thermal sensor.
