In order to test and monitor the operational stability and conditions of various energy, and manufacturing systems and their components, development of accurate sensors capable of operating at temperatures in excess of 1000 °C in various environments for long durations is required. In addition, many of these harsh-environment systems do not permit sensors to be directly inserted due to possible undesirable chemical interactions. In this work were developed high-temperature sensors using doped lanthanum chromites-refractory based composites synthesized by a mixed-oxide route. Different electrode printing approaches were explored. The chemical stability of the sensors was characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM). The Seebeck coefficients were determined by thermoelectric voltages measurements at temperature up to 1400 °C.
