Abstract

采用Mn2.3Co3.7ZnxCuyO4(x=0、0.03、0.06;y=0、0.05、0.08、0.1、0.2)体系制备负温度系数热敏电阻(NTCR),并通过EDS、SEM、FTIR研究了样品的微观结构和导电机理。结果表明,Mn-Co-O体系通过掺杂ZnO、CuO可以制备低阻高B型NTCR,当x=0.03,y=0.05可得到期望的电学参数。其中,Zn存在于四面体间隙,可以提升阻值B值;Cu同时存在于四面体间隙和八面体间隙,可以降阻值B值,部分CuO在晶界发生偏析。

Other Abstract

Series of Mn2.3Co3.7ZnxCuyO4(x=0,0.03,0.06;y=0,0.05,0.08,0.1,0.2)were used as negative-temperature-coefficient(NTC)thermistor.The microstructure and electrical properties of the samples were studied by EDS,SEM and FTIR.The results indicate that series of Mn-Co-O NTC ceramics with the relatively low electrical resistivity and high B constant were obtained by adding ZnO,CuO,when the x=0.03,y=0.05 led to the desired electrical parameters.The added Zn+ cations have a strong tendency to place themselves on the octahedral sites of the spinel lattice and lead to an increase in electrical resistivity and the B constant,but Cu2+ ions occupy both octahedral and tetrahedral sites and cause an decrease in those parameters.At the same time,we find that segregation of CuO occur at the grain boundary.
