Abstract

MéTODO PARA FABRICAçãO DE ELETRODOS DE GRAFITE PARA PROCESSOS ELETROLìTICOS. A presente invenção refere-se a um método para a fabricação de eletrodos de grafite com um revestimento preponderantemente de metal nobre para processos eletrolíticos, especialmente para a eletrólise de ácido clorídrico, na qual a superfície de um eletrodo de grafite é revestida com uma solução aquosa de um composto de metal nobre, e em seguida é temperada na presença de gases redutores e/ou quase inteiramente livres de oxigênio sob 150 a 650°C.
