Abstract
Publisher Summary This chapter mentions that the most widely accepted aluminum anode alloys contain mercury or indium as elements responsible for surface activation. Indium is second to mercury in this application followed by tin, magnesium, cadmium, and bismuth, with the latter elements not necessarily listed in their order of importance. Technical knowledge involves the melting/casting of aluminum alloys with ternary additions of elements belonging to the groups IA, IIA, and IIB from the periodic table, and the implementation of electrochemical techniques, which are adequate for the evaluation of the current efficiency of the anode. The chapter discusses electrochemical behavior of new ternary aluminum alloys as sacrificial anodes.
