Abstract
Abstract A dielectric material particularly suited for use in an electrical capacitor. The material has a constituent with particular metals combined with lead niobate. This constituent is dispersed in a ceramic matrix and can be readily deposited as a layer by screen printing techniques. The electrical capacitor may be supported on a substrate and may comprise more than one dielectric layer.
