PbO2 Titanium-supported anodic coating Why lead dioxide.PbO₂ combines anodic stability with high oxidation potential. Its coating structure is matched to the electrolyte and operating window. | High oxidation potentialHigh oxygen-evolution overpotential supports electrochemical oxidation and selected synthesis processes. Conductive, current-bearing surfaceThe PbO₂ working layer distributes industrial current across the active electrode area. Dimensional and chemical stabilityThe insoluble coating helps maintain electrode geometry in compatible acidic and oxidative environments. |
β-PbO₂ catalytic layer α-PbO₂ dense layer Noble-metal oxide transition layer TA1 / TA2 titanium substrate Structural and conductive foundation | PbO₂ active working layerSequential electrodeposition forms a dense α-PbO₂ inner layer and a porous β-PbO₂ catalytic surface, combining coating integrity, active area and electrochemical performance. Noble-metal oxide transition layerFormed by high-temperature thermal decomposition, the interlayer shields the titanium, limits passivation and strengthens adhesion of the PbO₂ coating. TA1 / TA2 titanium substrateCommercially pure titanium provides a lightweight, mechanically strong and corrosion-resistant foundation for current conduction. The substrate can be recoated and reused when suitable. |
Extended operating lifeThe multilayer coating is engineered for continuous anodic load. Reference applications indicate approximately 1–2 times the life of conventional lead-alloy anodes, depending on operating conditions. | Mesh geometry for uniform electrolysisThe three-dimensional mesh increases active area and supports electrolyte flow and uniform current distribution. |
Less sludge and lower maintenanceThe insoluble structure reduces lead-sulfate shedding, bottom sediment and routine tank maintenance. | Supports high-purity cathode copperFewer anode-derived particles and no Sn, Sb or Ag alloying constituents help limit contamination. Validated processes can achieve 4N5 or Grade A cathode copper. |
Lightweight, configurable constructionLighter than solid lead-alloy structures, it is available as mesh, plate or tube with customized dimensions and connections. |
