The primary goal of this Phase II program was to improve the dielectric breakdown strength of ceramic multilayer capacitors MLCs in order to improve capacitive energy storage at liquid-nitrogen temperatures. A secondary goal was to explore the reproducibility of a field-enforced state- switching effect discovered in the Phase I program. The ceramic composition involved in these programs is designated as CPN17 and has a dielectric constant in the range 8,000-10,000 at 77 K. Several variations in conventional ceramic- processing parameters were studied, leading to systematic improvements in the breakdown strength at 77 K 160 to 250 to 400 kVcm.
