Titanium anode, also known as titanium electrode, is generally referred to as MMO (Mixed Metal Oxide) titanium-based metal oxide coated anode at home and abroad, or DSA (Dimensionally Stable Electrode) size and shape stable anode. It is made of titanium (plate, rod, wire, tube, mesh) as the substrate, coated with a precious metal coating on the titanium substrate, making it have good electrocatalytic activity, conductivity, and corrosion resistance. Compared with graphite anodes and lead anodes, titanium anodes have the following advantages:
- Stable electrode size: The distance between electrodes does not change during the electrolysis process, ensuring that the electrolysis operation is carried out under stable voltage conditions.
- High electrolysis efficiency: Low working voltage, low energy consumption, and DC power consumption can be reduced by 10%–20%.
- Long working life: Surface precious metals (iridium, ruthenium, platinum) have oxidation resistance, so titanium anodes have strong corrosion resistance, with an average life of 5–7 years, while graphite anodes only have 8 months.
