The Three Major Application Areas And Characteristics Of Titanium-based Iridium-tantalum Coated Anodes

Titanium-based iridium-tantalum coated anodes (hereinafter referred to as iridium-tantalum anodes) possess excellent oxygen evolution electrocatalytic activity and long service life, making them internationally recognized as the best oxygen evolution anodes available. They have been widely used in fields such as electrolytic copper foil, PCB copper plating, aluminum foil formation, continuous galvanizing, trivalent chromium plating, acid copper plating, and nickel plating.

The three main application areas for iridium-tantalum anodes are primarily electrolytic copper foil, PCB copper plating, and aluminum foil formation. Due to significant differences in the electrolysis conditions across these fields, the performance requirements for the anode coating also vary. Therefore, even though iridium-tantalum anodes are used in all cases, there are some differences in the focus of the coating design. The following outlines the differences and characteristics of iridium-tantalum anodes in these three major application areas:

Titanium Anodes for Electrolytic Copper Foil

The biggest characteristic of titanium anodes for electrolytic copper foil is the use of high current density, imposing extremely strict requirements on the uniformity of the anode coating and the uniformity of the electrolytic copper foil product. Typically, the failure of titanium anodes is due to poor conductive uniformity of a particular anode plate or a specific area of the coating, causing the produced electrolytic copper foil to fall short of uniformity standards, leading to the anode being taken out of service.

Titanium Anodes for PCB Copper Plating

The biggest characteristic of titanium anodes for PCB copper plating is that the application process focuses on the consumption of PCB copper plating additives. The main reason for anode failure is the excessive consumption rate of additives, rather than a decline in the anode's electrical conductivity.

Titanium Anodes for Aluminum Foil Formation

The biggest characteristic of titanium anodes for aluminum foil formation is their application in high-concentration organic systems with relatively high cell voltages. The main reason for anode failure is excessive wear of the anode coating, leading to a severe decline in electrical conductivity.
