The purpose of the research is the development of ceramic materials with high dielectric constant and high dielectric strength values, and suitable for use as dielectrics in capacitors capable of storing large amounts of energy in small volumes. The theory that high density in a ceramic disk would cause high dielectric strength proved to be false. An examination of capacitors with the highest dielectric strengths disclosed that they had small grain size. A series of samples was prepared with Ba and Co additions which suppress grain growth. Two hundred 1-inch diameter capacitors accumulated over a two-year period were evaluated and are reported in detail. Some of the thoretical considerations originally used to guide the development of the storage capacitor are reviewed. An effort to evaluate methods of electroding other than evaporated silver was continued. Experiments on isostatic pressing are described. (For preceding period see AECU-4286.) (W.D.M.)
