Description
<EMI ID=1.1> squelette* <EMI ID=2.1> <EMI ID=3.1> par un squelette conducteur d'électricité, dans lequel sont noyés des graine de métal de. Raney. Ces électrodes ont été <EMI ID=4.1> gâteuse. Pour établir de telles électrodes, on doit d'abord obte- <EMI ID=5.1> broyer ce produit en poudre fine. Partant de cette poudre de métal de Raney, on sélectionne l'intervalle granulome trique <EMI ID=6.1> surer des degrés d'activité élevés, des méthodes de traitement ' particulières, telles que, par exemple, une activation régie par le potentiel; d'autre part, elle exige, pour la préparation <EMI ID=7.1> ce du métal de Raney, mais uniquement la structure de surface <EMI ID=8.1> <EMI ID=9.1> <EMI ID=10.1> <EMI ID=11.1> <EMI ID=12.1> <EMI ID=13.1> Il en résulte une augmentation notable de la charge admissible, à polarisation égale. <EMI ID=14.1>
Claims (1)
- <EMI ID=15.1> <EMI ID=16.1> <EMI ID=17.1><EMI ID=18.1>10. Procédé suivant la revendication 1, caractérisé en ce que les poudres de nickel et d'aluminium sont Mélangées tous une pression mécanique et comprimées de façon à coatituer un<EMI ID=19.1><EMI ID=20.1>11. Procédé suivant la revendication 1, caractérisé en ce que le mélange de poudres est pourvu d'un élément conducteur d'électricité sous la forma d'une toile, d'une résille ou d'une<EMI ID=21.1>ment au procédé suivant la revendication 1.
