It's engineered to efficiently conduct electrical current through an electrolyte at significantly elevated current levels per unit area, driving electrochemical reactions with minimal energy loss and extended operational life.

Types of Titanium Anodes: From MMO to Platinum-Coated

The choice of coating is paramount, tailored to the specific electrochemical reaction and operating conditions. Two main types dominate the high current density landscape:

• Mixed Metal Oxide (MMO) Anodes: These are the workhorses. MMO coatings, often composed of iridium oxide, ruthenium oxide, and titanium oxide, offer excellent electrocatalytic activity and stability. They're particularly effective for chlorine evolution, oxygen evolution, and wastewater treatment. Their robust nature means they can stand up to a real beating.
