Lead Dioxide Coated Titanium Anode

Lead Dioxide Coated Titanium Anode(Ti/PbO₂is 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 (Ti-PbO2)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.

The advantage of TI based PbO2 electrodes:

1.Light weight, high strength;
2. Ti/PbOanode using Ti mesh as substrate can reduce the electrolyte flow resistance, improve the efficiency of current, especially under high current density can effectively prevent anode from overheating.
3. Excellent conductivity, strong adhesion strength of the coatings and substrate, prevent substrate passivation, low cell voltage, long operating life.
4. Using doping, composite plating technology etc. effectively reduce the internal stress of the coatings, prevent coatings from falling off in use, and improve the stability of the anode and service life.
