xLaCoO3-(1 − x)CaCu3Ti4O12 (0.02 ≤ x ≤ 0.15): a NTC thermosensitive ceramic with controllable electrical properties
In this study, a series of perovskite-phase xLaCoO3-(1 − x)CaCu3Ti4O12 [xLC-(1 − x)CCTO, with x = 0.02, 0.04, 0.08, 0.15] negative temperature coefficient (NTC) ceramics were fabricated by a solid-state reaction ...
