Sensitivity and Accuracy of Dielectric Measurements of Significantly Improved Coupled Capacitive-Dependent scheelite crystal

Abstract

The ability of thermistor to exhibit linear electrical behaviours is crucial for minimising circuit design complexity. To create high performance electronic ceramics, phase formation modulation is crucial. By using a solid-state reaction technique, novel linear high-temperature thermistors based on BaWO4 ceramics were created, resulting in an internal conducting network and linear electrical characteristics. In the temperature range of 573 K to 773 K, the ceramics showed negative temperature coefficient (NTC) thermistor properties. They had an excellent linear resistance-temperature (R-T) combination. The process behind linear electrical behaviours has been analysed using a parallel conductive model in combination with a comprehensive impedance and dielectric study. This strategy might be applied more generally to create linear high-temperature thermistors with a large temperature range.
