Dielectric and non-Ohmic properties of CaCu3Ti4O12 ceramics modified with NiO, SnO2, SiO2, and Al2O3 additives

In order to conciliate dielectric and non-Ohmic properties of CaCu 3 Ti 4 O 12 (CCTO) ceramics, NiO, SnO 2 , SiO 2 , and Al 2 O 3 were added as sintering aids to promote the grain growth of CCTO ceramics. Microstructure, dielectric properties, and non-Ohmic behavior of the CCTO ceramics were investi...
