US 2012/0071314 A1 · ENERGY STORAGE CERAMIC DIELECTRIC COMPONENT AND METHOD THEREOF

Abstract

The present invention is a new composition of matter and can be used as components of a capacitor. The dielectric properties possess in this material has improved tremendously as compared to the existing component. The finding of high dielectric permittivity in the present invention ceramic according to its formulation and processing technique that can operate or use at wide range frequencies and temperatures are very useful in electronic and electrical devices. The present invention is best for applications at the range of temperatures. The permittivity is recorded at 1 kHz are between ˜20,000 to ˜54,000 and almost constant over three decade of frequency. Thus, the dielectric permittivity obtained can be used as energy storage, sensor, electric filter, etc., besides minimizing the devices size.
