Abstract

The article delves into the characterization of NiO-based ceramics modified with Y2O3/BiSbO3 for NTC thermistor applications. It discusses the traditional and recent advancements in NTC thermistors, focusing on the electrical properties and aging stability of NiO ceramics. The study reveals that Y2O3/BiSbO3 modification can significantly enhance the electrical stability and adjust the resistivity of NiO ceramics, making them promising for various electronic applications. The research methodology includes XRD, SEM, EDS, and XPS analyses, providing comprehensive insights into the microstructure and electrical behavior of the ceramics. The results show that the modified ceramics exhibit typical NTC characteristics and high thermal sensitivity, with room temperature resistivity ranging from 1143 to 19,188 Ω·cm. The aging stability test demonstrates that the ceramics with BSO modification exhibit excellent electrical stability, with a resistance change rate of only 0.21% after 800 hours of aging at 150°C. This research highlights the potential of Y2O3/BiSbO3-modified NiO ceramics for practical NTC thermistor applications, offering valuable contributions to the field of materials science and electronics.
