ELECTRODE FOR ELECTROLYSIS

摘要

An anode comprising an electroconductive substrate provided with a (Ru-Sn)O2 solid solution coating is useful in brine electrolysis. The improved coating has a composition of (i) 3 to 45 mol % of ruthenium oxide, (ii) 0.1 to 30 mol % of at least one member selected from metallic platinum, platinum oxide, and iridium oxide, and (iii) 50 to 96.9 mol % of tin oxide which may be partially replaced by antimony.
