Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
An electrode for use in an electrolytic reaction comprising a base of electrically conductive film-forming metal in solid form having thereon a mixed coating material of an electrically conductive coating material effective for carrying out electrolysis and protecting coating material consisting of at least one metal oxide of a single film-forming metal, the protecting coating material acting during electrolysis in a cell to protect the conductive coating material against the cell conditions, the conductive coating material being at least one material from the group consisting of gold, silver, platinum, palladium, iridium, ruthenium, osmium, rhodium, iron, nickel, chromium, copper, lead, manganese, and nitrides, carbides and sulfides thereof, and said group further consisting of oxides of gold, silver, iron, nickel, chromium, copper, lead and manganese.
Claim 2
Dependent Claim
123 words
An electrode for use in an electrolytic reaction comprising a base of electrically conductive film-forming metal in solid form having thereon a mixed coating material of an electrically conductive coating material effective for carrying out electrolysis and protecting coating material consisting of at least one metal oxide of a single film-forming metal, the protecting coating material acting during electrolysis in a cell to protect the conductive coating material against the cell conditions, the conductive coating material being at least one material from the group consisting of gold, silver, platinum, palladium, iridium, ruthenium, osmium, rhodium, iron, nickel, chromium, copper, lead, manganese, and nitrides, carbides and sulfides thereof, and said group further consisting of oxides of gold, silver, iron, nickel, chromium, copper, lead and manganese.
Claim 3
Dependent Claim
27 words
An anode as claimed in claim 1 in which the base is metal and the protecting coating material is an oxide of the metal constituting the base.
