Ag-migration effects on the metastable phase in CaCuTiO capacitors.

The silver migration effect into the metastable phase forms a micro-electric path, to enhance the relative dielectric permittivity of CaCuTiO ceramics for electronic devices. Controlling the sintering time uniquely develops the metastable phase of as-sintered CaCuTiO ceramics. A post-heating process that applies the migration of silver into the metastable phase increases the relative dielectric permittivity.
