摘要

在传感器应用方面，对Pr0.8Na0.2MnO3 （PNMO）和Pr0.8K0.2MnO3 （PKMO）的电学性能进行了比较研究。确定样品在技术应用中的有用性的具体参数被推断和分析。所研究样品的电阻温度系数TCRmax最大值为PNMO的TCRmax = 20.88% K−1，PKMO的TCRmax = 3.7% K−1。PNMO的TCRmax大于PKMO的TCRmax，表明PNMO作为传感器系统的首选。在180 ~ 400 K范围内，计算了热敏电阻常数β （PNMO为β = 1249 K， PKMO为β = 1764 K）、灵敏度因子α （PNMO为α = -0.0196， PKMO为α = -0.0138）和稳定性因子SF （PNMO为SF = 5.24， PKMO为SF = 3.2）参数，确定了PNMO和PKMO化合物是热敏电阻应用的合适候选化合物。

Regarding application in sensor; a comparative study of electrical properties of Pr0.8X0.2MnO3 (X=Na and X = K) ceramics

Regarding application in sensor, a comparative study of electrical properties of Pr_0.8Na_0.2MnO₃ (PNMO) and Pr_0.8K_0.2MnO₃ (PKMO) is conducted. Specific parameters defining the usefulness of samples in technological applications are inferred and analyzed. The maximum values of the temperature coefficient of resistance TCR_max for the studied samples are TCR_max = 20.88 %K⁻¹ for PNMO and TCR_max = 3.7 %K⁻¹ for PKMO. TCR_max for PNMO is greater than that of PKMO which shows the preference of PNMO as the system used for sensors. Between 180 K and 400 K, the thermistor constant β (β = 1249 K for PNMO and β = 1764 K for PKMO), the sensitivity factor α (α = -0.0196 for PNMO and α = -0.0138 for PKMO), and the stability factor SF (SF = 5.24 for PNMO and SF = 3.2 for PKMO) parameters are calculated to confirm that PNMO and PKMO compounds are suitable candidates for thermistor applications.
