Abstract Anodic formation of metal oxide on the metal substrates have been use in various industrial fields to improve of corrosion resistance, heat insulation, anti-reflecting and decorate metal surface. Furthermore, anodization methods allows to formation of metal oxide nanostructure with one or three dimensionally. The anodic oxide nanostructures also have various advantages due to its high specific surface areas, high electron conductivity with vertically aligned geometry. For these reasons, anodization have been studied in several decades. To form anodic metal oxides, several parameters are concerned such as composition of electrolytes, applied potential or current, and reaction temperatures. In general, porous anodic Al2O3 are formed in acidic electrolytes, anodic TiO2 nanotubes are formed in fluorine containing electrolytes at room temperatures. In this presentation, we introduce new anodization approach which is carried out in phosphate contained glycerol electrolyte at high temperatures. The anodization methods are easy to control chemical etching rate which leads to allowing unusual metal oxide formation and nanostructuring of Al, Ni and stainless steel.
