Enhanced aging and thermal shock performance of Mn1.95−x CO0.21Ni0.84Sr x O4 NTC ceramics

Abstract The Mn1.95−x Co0.21Ni0.84Sr x O4 (MCNS) (0 ≼ x ≼ 0.15) based negative temperature coefficient (NTC) materials are prepared by co-precipitation method. The replacement of Mn by Sr plays a critical role in controlling the lattice parameter, relative density, microstructure, and electrical pro...
