Lead Dioxide Coated Titanium Anode

Lead Dioxide Coated Titanium Anode

The lead dioxide coated titanium anode is an electrode of massive lead dioxide in an extremely hard and dense form. It is produced by electrodepositing on titanium base material from an aqueous lead salt bath. Lead dioxide coated titanium anode is prepared by electroplating a stable and compact lead dioxide coating layer on a titanium substrate. Owing to its superior corrosion-resistance, high overpotential for the oxygen evolution reaction, and strong ability of oxidation in aqueous solution electrolysis properties, lead dioxide coated titanium anode is comparatively performing better than other anodes in many electrochemical fields.

The lead dioxide coated titanium anode UTron manufactured has low resistivity, stable chemical properties, strong oxidation resistance (strong oxidation ability during electrolysis in aqueous solution); high corrosion resistance (higher stability in strong acid HzS04 or HN03); high oxygen overpotential; good electrical conductivity, and can pass high currents, etc. It has a three-dimensional structure coating (noble metal oxide + α-PbO2 + β-PbO2), which substantially improves the bonding of the plating. It has a strong binding force, and strong oxidation ability when electrolyzed in an aqueous solution. Titanium substrate coated lead dioxide anode has been widely used in electroplating, electrowinning, wastewater treatment, and other fields.
