“…Independent of the detailed nature of the mate- Sintered titanium anodes (STA) have been developed by Sigri. In these electrodes, an intermediate layer of sintered titanium suboxide is applied between the titanium substrate and the coating, which gives improved mechanical stability, excellent adhesion to sintered titanium structures, and increased active surface area [205], [206]. Imperial Chemical Industries (ICI) has used these anodes in large-scale production since 1971.…”
