Descriptions of Titanium MMO Sheet
Titanium MMO (Mixed Metal Oxide) Sheet is a titanium-based electrode material coated with a layer of mixed metal oxides such as ruthenium, iridium, platinum, or tantalum. It offers excellent electrochemical performance, high durability, and superior corrosion resistance, making it ideal for use in harsh chemical environments. The MMO coating provides excellent catalytic properties for oxygen and chlorine evolution reactions, ensuring long service life and stable performance in various electrolytic processes.
