Ceramic dielectric materials for high energy storage capacitors
WO 93/11548. Multilayer capacitors comprise layers of a dielectric material interleaved with metallic electrodes. To improve the energy storage of such capacitors when operating in field strengths greater than 20 kV/mm, the dielectric material is a modified ceramic material comprising a base material and an additive. The base material is a ferroelectric ceramic material having (i) its ferroelectric Curie temperature either greater than or lower than the working temperature of the capacitor,...[Show more]
