Product Overview
IrTa Tubular Titanium Anode is a high-performance mixed metal oxide (MMO) titanium electrode manufactured using high-purity titanium tubular substrate coated with iridium oxide and tantalum oxide. The electrode is specially designed for demanding oxygen evolution and industrial electrolysis applications requiring excellent catalytic performance, high corrosion resistance, and stable long-term operation.
Compared with conventional flat plate electrodes, the tubular titanium anode structure provides several important advantages including improved electrolyte circulation, enhanced gas release efficiency, larger effective reaction area, and more uniform current distribution.
The iridium-tantalum MMO coating system provides excellent electrocatalytic activity for oxygen evolution reactions (OER). Iridium oxide significantly improves electrochemical efficiency and reduces oxygen evolution overpotential, while tantalum oxide enhances coating stability and corrosion resistance under aggressive electrochemical conditions.
Due to its excellent structural design and advanced coating technology, IrTa Tubular Titanium Anode is widely used in PEM water electrolysis, electrochemical oxidation, industrial wastewater treatment, electrochemical disinfection, and advanced industrial electrolysis systems.
The tubular structure also provides excellent mechanical strength and dimensional stability during long-term operation. In high-current electrolysis systems, the tubular design improves electrolyte flow efficiency and helps reduce local current concentration, thereby improving overall electrochemical system performance.
As industries continue to demand high-efficiency and long-lifetime electrode materials, IrTa Tubular Titanium Anode has become an important solution in modern industrial electrochemical engineering applications.
