Dimensionally Stable Anodes
Dimensionally stable anodes (DSA) were developed in the mid-1960's for the chlor-alkali industry.
They are called dimensionally stable because they utilize precious metal containing electrocatalysts, like RuO2,
coated on titanium. The titanium substrate is corrosion resistant in the chlorine generating environment
which allows for the structure to maintain its dimensional tolerance during its life unlike the graphite anodes
they replaced. Since their introduction into the chlor-alkali industry, DSAs have found economic application in chlorate generation,
water disinfection, pool chlorinators, organic destruction, electrogalvanizing, electrotinning and metal plating.
