© 2019 Elsevier B.V. Ba 0.85 Ca 0.15 Zr 0.1 Ti 0.9 O 3 -based ceramics with doping of Ca 3 Co 4 O 9 , CaMn 0.98 Nb 0.02 O 3 , and Zn 0.98 Al 0.02 O were fabricated. CaO and CaCO 3 secondary phase were observed in all doped ceramics. These phases caused vacancies of Ca ions, which became associated...
