Abstract

"CATODO PARA USO EM CéLULAS ELETROLìTICAS E APLICAçãO DO MESMO". São descritos um catodo cuja superfície ativa é constituída por uma determinada classe de ligas metálicas e a sua aplicação em processos eletrolíticos. Mais especificamente, a presente invenção se refere a catodos, que apresentam baixa sobretensão de hidrogênio e elevada resistência a corrosão quando utilizados nas reações de eletrólise da água e de soluções aquosas de cloretos de metais alcalinos."CATODE FOR USE IN ELECTRONIC CELLS AND APPLICATION OF THE SAME". A cathode is described whose active surface consists of a certain class of metallic alloys and its application in electrolytic processes. More specifically, the present invention relates to cathodes, which have low hydrogen overvoltage and high resistance to corrosion when used in the reactions of water electrolysis and aqueous solutions of alkali metal chlorides.
