PEM FOR PRODUCTION OF FLUORINATED BARIUM TITANATE CAPACITORS FOR OPERATION TO 200C.

Ceramic capacitors, MIL style CK63, capable of operating at 200C, were manufactured from a fluorinated dielectric of which BaTiO3 was the predominant material, 87%, other materials being CaZrO3, 12.7%; Fe2O3, 0.1%; and Ce2O3, 0.2%. A low voltage, miniaturized, fluorinated capacitor, having a thin dielectric of the same composition as the CK63 capacitors, was also manufactured for 200C operation. Fluorination of a dielectric was accomplished by re-firing the matured dielectric in a fluoride atmosphere.
