Outline of Final Research Achievements

In this project, we examined the effects of trace ingredients in dimethylsulfone baths on the electrodeposition of Al, and developed additives working as brighteners and purifiers. Main results are as follows: 1) bright Al films could be electrodeposited from the baths with the addition of triethylenetetramine; 2) the influence of water in the baths on the electrodeposition of Al and a method for the removal of the water were elucidated; 3) the effects of the simultaneous addition of triethylenetetramine and dimethylamine hydrochloride were elucidated; 4) a novel organic solvent bath for the electrodeposition of Al was developed.
