Empirical Modeling of Nano Alumina Combustion Synthesis Using Box-Behnken Statistical Design

Abstract

Nano-sized Al₂O₃ has been prepared by combustion synthesis. The process has been empirically modeled using Box-Behnken design method for the first time. The products were characterized by XRD, BET, TGA, FESEM, and TEM analyses. Results demonstrated that the nano alumina powders had specific surface areas between 37 m²/g and 113 m²/g. The synthesis of alumina was modified in order to achieve higher specific surface area (154 m²/g). This method has been resulted nano fibers with the length and diameter of about 150 and 10 nm, respectively.
