Abstract
Provided are processes for the manufacture of capacitors. It is found that by using a nickel foil as the substrate and one electrode of the capacitor and by controlling the oxygen partial pressure in the range of 10−8 to 10−10 atmospheres during the crystallization heat treatment of the barium titanate, the leakage current can be maintained at adequate values without a reoxygenation step.
