摘要: 研究了Mn - Co -O体系通过掺入适量Zn0,采用最佳的烧结温度,可制备低阻高B型NTCR (负温度系数热敏电阻),并通过XRD、SEM研究了样品Mn_l.14Co_1.83Zn_0.030_4在不同烧结温度下的微观结构和电学特性。结果 表明:Mn - Co - Zn -0体系在T=1100~12000C很宽的温度范围可只存在尖晶石结构,同时具有高的激活能。样品Mn_l.14Co_1.83Zn_0.030_4在 烧结温度T=llOOC时存在最小电阻率,而B仍保持在4046K左右。因此,由其制成的单层片式NTCR可替代某些具有内电极的叠层器件。
英文摘要: Series of Mn - Co - O NTC ceramics with the relatively low electrical resistivity and high B constant were obtained by adding ZnO and controlling sintering temperature.The microstructure and electrical properties of Mn1.14 Co1.83Zn0.03O4 ceramics were investigated at different sintering temperature.The results indicate that the samples exhibited the high activation energy and formed mono - spinel oxide at the temperature of 1100 - 1200℃.Also,at a given 1100℃ ,the resistivity decreased to a minimum value,but a value of 4046K of the B constant was maintained.So the Mn1.14Co1.83Zn0.03O4 thermistors could be applied to single chip temperature sensor instead of some multilayer NTC thermistors with inner electrodes.
