Synthesis of anodic aluminum oxide (AAO) at relatively high temperatures. Study of the influence of anodization conditions on the alumina structural features

► Nanoporous alumina has been fabricated by anodization at elevated temperature. ► Increased temperature of anodization considerably shortened the process. ► Qualitative analysis of operating parameters influence on pores arrangement has been done. ► Influence of operating parameters on the current density has been studied. ► Influence of operating parameters on the alumina geometry has been studied.
