Development History Of Titanium Anodes

In 1967, Beer invented a way to make thin films of metal oxides on titanium, one of which was a concrete example of ruthenium oxide, used as an anode for the hydrolysis of salt, which revolutionized the chlor-alkali industry. This coating is still widely used in various electrochemical chlorine evolution reactions. With the in-depth research on a variety of platinum group metals and their oxides, Iridium tantalum mixed metal oxide coatings were developed successfully in the 1970s and gradually began to be used in electrochemical oxygen evolution reactions. Until now, titanium anodes rely on its superior performance, widely used in a variety of electrochemical fields, including chemical (chlor-alkali industry), electrolytic organic synthesis, electroplating, cathodic protection, industrial and civil electrolytic chlorine disinfection and other applications.
Since the 1990s, titanium anodes have been used in PCB copper plating process and further developed and perfected in the first decade of this century. In the last 10 years, with the improvement of PCB manufacturing capability, titanium anode has gradually replaced soluble anode - phospho-copper ball with its unique advantages. According to different electroplating requirements, titanium anode can be used not only for DC electroplating, but also for reverse pulse electroplating. In the future, titanium anodes will continue to be developed to adapt to new plating conditions as the requirements of the copper plating process are further improved.
