Abstract
An electrode having a lead dioxide coat electrodeposited on a porous ceramic substrate is manufactured by soaking a porous ceramic substrate in an aqueous lead (II) salt solution and thereby allowing lead oxide to be deposited in the porous surface layer and on the surface of the substrate thereafter soaking said porous ceramic substrate in a persulfate solution to cause oxidation of the lead oxide so deposited therein and thereon and effecting electrolysis in an aqueous lead (II) salt solution by using said lead dioxide-coated substrate as the anode and the aqueous solution as the electrolyte and thereby causing lead dioxide to the additionally electrodeposited on said lead dioxide coat. The electrode manufactured as described above excels in corrosion-resisting property and therefore proves quite advantageous as an electrode for use in the electrolysis of aqueous solutions.
