Abstract
1308334 Electrolytic capacitors P R MALLORY & CO Inc 5 March 1970 [6 March 1969] 10708/70 Heading H1M In an electrolytic capacitor the substantially non-aqueous electrolyte comprises a polar organic solvent containing an ionisable solute and chromate or dichromate radicals. The radicals, preferably constituting 0À01 to 2À5% by weight of the electrolyte, may be introduced as an acid, metallic or non-metallic salt, e.g. ammonium or amine chromates or dichromates or complexes thereof and may be at least partially ionized. The solvent may be a glycol ether, cyclic or other ring alcohol, or N-substituted amide. The solute may be boric, phosphoric, maleic, benzoic, malonic or tartaric acid or mixtures of certain of these, at least partially neutralized with ammonia, alkylamine, alkanolamine, a guanidine base, pyridine, butidine or picoline.
