Systematic investigation has been made on the structure and dielectric properties of Mn CO 3 ‐doped barium titanate‐based X8R ceramics, to reveal the relationship between the manufacturing process and dielectric properties. The dielectric ceramic sintered at 950°C showed high permittivity and low dielectric loss, meeting X8R specifications. Transmission electron microscopy and EDS analysis were used. The results suggested that the temperature‐stable BaTiO 3 ‐based X8R ceramics with the good dielectric properties can be prepared through the BaTiO 3 calcined at 1150°C and doped with 0.7 wt% Mn CO 3.
