A solid solution containing 35% SrTiO/sub 3/ and 65% BaTiO/sub 3/ was formed into ceramic disks with densities as high as 99% of the theoretical value. Contouring of the surfaces of the capacitors to prevent edge breakdown was accomplished by ultrasonic and diamond-wheel grinding. Application of electrodes by evaporation of metallic silver proved satisfactory for most of the testing. The highest measured dielectric strengths were slightly in excess of 400 v/mil for one-inch capacitors and 200 v/mil for five-inch disks. In high-density ceramic bodies, the importance of dielectric breakdown in microscopic pores of the medium was found to be subordinate to breakdown by means of excessive conduction through the grain boundaries.
