Product Overview

The Mixed Metal Oxide (MMO) Coated Tubular Anode is manufactured using Grade 1 Titanium with a purity of 99.6% as the substrate material.
It is coated with a Ruthenium–Iridium (Ru–Ir) or Iridium–Tantalum (Ir–Ta) oxide catalyst layer, which provides exceptional electrocatalytic activity, chemical stability, and durability in various electrochemical applications.

This type of anode is widely used in chlor-alkali, cathodic protection, water treatment, and electroplating systems, ensuring long service life and consistent performance.

Platinized Metal Anode Background

Platinum (Pt) is a noble metal with outstanding corrosion resistance, thermal conductivity, and catalytic properties.
However, due to its high cost, solid platinum anodes are rarely used in industrial applications.
Instead, Platinized Metal Anodes (Pt Anodes) are produced by electrodepositing platinum onto specially treated metal substrates such as Titanium, Niobium, Tantalum, or Zirconium.

This electroplating process combines the superior electrochemical performance of platinum with the mechanical strength and cost efficiency of the substrate — offering an economical and high-performance anode solution.
