In this research, anodizing method at constant temperature of 0oC and in constant current in the phosphoric acid electrolyte was used to synthesize the nano-porous alumina templates with desired pore diameter. A new system for controlling temperature as well as for Creation homogeneous conditions in electrolyte solution has been used. Designing experiments and identifying important variables on the diameters of synthesized alumina pores was carried out using the central composition design and the response surface method was used to evaluate the interaction of the parameters and determine their importance on the diameter of the synthesized porous anodic alumina pores. The intensity of the applied current, the electrolyte concentration and the duration of the anodizing was considered as variable parameters. FE-SEM images were used to determine the diameter of the pores. The main purpose of this research is to provide a model for determining the appropriate laboratory conditions for the synthesis of nano-porous anodic alumina templates with desired pores diameter.
