Abstract
- Negative Temperature Coefficient (NTC) thermistors, known for their high sensitivity and fast response, find wide applications in national economy, military, aerospace and various other fields. The study of NTC thermistors with linear temperature-resistance is of great significance in streamlining circuit designs and developing high-performance electronic ceramics. This study focuses on the synthesis of a linear thermistor material in x Al 2 O 3 -(1- x)CdSnO 3 system by a solid-phase reaction method. Through the introduction of th high-resistance Al 2 O 3 phase, a three-dimensional conductive network is established with Al 2 O 3 and CdSnO 3 , resulting in the acquisition of linear electrical properties. These properties have exhibited excellent linear NTC variation within the temperature range of 308 K–458 K. Notably, at x = 0.2, the thermistor shows the highest linearity (R 2 = 0.9984). Additionally, the complex impedance spectral analysis has helped build resistive and capacitive conductivity models revealing the linearization mechanisms. [ABSTRACT FROM AUTHOR]
