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.
