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 &#x2dc;20,000 to &#x2dc;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.

Energy storage ceramic dielectric component and method thereof

The present invention relates to a porous bioceramic composition for bone repair and method of fabrication of the same. 3D-scaffolds were fabricated with a novel micro- and macro-architecture. Porous scaffolds based on dextrin, dextran, gelatin and biomineral (CaCO) powder were fabricated by heating and freeze-drying methods. Fabrication of different compositions of porous scaffolds (20, 30 wt % of gelatin, 20, 40 wt % dextrin, 30, 40, 50, 60 wt % dextran bounder with the constant quantity of CaCO50 g). The scaffolds properties were characterized by x-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and compression tests.
