Electroceramics consist of dielectric ceramics, piezoelectric ceramics and ferrites and microwave ceramics.
Dielectric ceramics and substrates are electrical insulators with dielectric strength, dielectric constant and loss tangent values tailored for specific device applications.
Electroceramics are ceramic materials that have been specially formulated for specific electrical, electro-magnetic, or optical properties. They include dielectric ceramics, electrostrictive ceramics, ferrite ceramics, garnets (ferromagnets), and piezoelectric ceramics.
Ferrite ceramics and ferromagnetic materials have dielectric and magnetic properties that are suitable for RF and microwave applications. They provide high electrical resistivity and low magnetic losses.
Piezoelectric ceramics produce an electrical charge when a load is applied and deformation occurs. Piezoelectric ceramics can also produce force or deformation when an electrical charge is applied.
