AbstractMn-substituted La2/3Cu3Ti4O12 negative temperature coefficient (NTC) ceramics were successfully prepared by the traditional solid-state method, and their microstructures and electrical properties were also investigated. XRD patterns showed that the ceramics before polishing were covered by a layer of Cu-rich phase. As the Mn content increased, the segregation of Cu-rich phase at the grain boundary decreased, which leads to the gradual increase of the grain boundary resistance. The linear electrical behaviors were slightly enhanced with increasing Mn content. The B-25/300-value and activation energy (E-a) increased gradually with increasing Mn content. The values of rho(25), B-25/300 and E-a of the sintered ceramics were in the range of 7.8 x 10(5)-6.2 x 10(6) Omega cm, 5751-6235 K and 0.496-0.538 eV, respectively. (C) 2020 Elsevier B.V.
