Noble metal electrodes do not stand the tests for anodic electro syntheses in technical applications. Mainly due to the high oxygen overvoltage lead dioxide can act as substitute. A novel process for the preparation of lead dioxide coated titanium anodes is described. The important procedure is a treatment of the clean titanium surface with a Ti(IV)-containing solution. By scanning electron microscopy it is established that three dimensional nucleation takes place. Lead dioxide anodes prepared following this process until now have livetimes of better than 3400 hours
