Title: Effect of Y2O3 addition on the electrical properties of BaTiO3-based NTC thermistors
Abstract: The influence of Y2O3 addition on the electrical properties and the microstructure of BaTiO3-based negative temperature coefficient (NTC) thermistors was studied. All the NTC thermistors prepared showed a linear relationship between log resistivity and the temperature, indicative of NTC characteristics. At a given BaTiO3 and BaBiO3 content, as the amount of Y2O3 in BaTiO3-based ceramics thermistors increased, the resistivity decreased to a minimum value and then increased again. Similarly, Y2O3 addition had the same effect on the coefficient of temperature sensitivity for those samples.
