Abstract

PROCESSO PARA PRODUçãO DE SUPERFìCIES DE óXIDO DE NìQUEL COM CONDUTIBILIDADE AUMENTADA. A presente invenção refere-se a um processo para produção de superfícies de óxido de níquel de material que contém níquel, sendo que a superfície de níquel é primeiramente desengordurada, subseqüentemente, asperizada por cerca de 10 minutos em uma solução de ácido clorídrico de 1%, sendo que por adição de solução de peróxido de hidrogênio, o procedimento é acelerado e torna-se perceptível um tingimento esverdeado do eletrólito, a superfície de níquel é lavada, o material é imerso em uma solução de lixívia alcalina 3,5 molar, misturada com cerca de 10% de peróxido de hidrogênio e ali mantido por 10 minutos, a superfície de hidróxido de níquel formada desse modo é secada em um processo térmico subseqüente e, a seguir, é oxidada adicionalmente pra óxido de níquel. A invenção compreende, ainda, a camada condutora de contato, que é produzida de acordo com o processo, bem como os eletrodos da mesma e o uso em processos da eletrólise de cloro-álcali, em células de combustível e em acumuladores.
