A dielectric is an electrical insulator that can be polarized by an applied electric field. In electronic ceramics, we aren't satisfied with just insulation; we want high permittivity (dielectric constant, or κ ).
Electronic ceramics, or electroceramics, are specialized materials designed to perform precise electrical, magnetic, or optical functions. Unlike traditional ceramics used for their mechanical strength, electronic ceramics leverage unique physical phenomena—such as high-temperature superconductivity and nonlinear dielectrics—to power modern technology.
