Application of Taguchi method in the optimization of process parameters for a sol–gel-derived nano-alumina film

In this study, the Taguchi method is used to find the optimal process parameter combinations for realizing both lower film thickness and crystallite size and higher film thickness and crystallite size in a nano-alumina film prepared by sol–gel route. The process parameters evaluated were the molar concentration of the sol, dipping time, and sintering temperature. An orthogonal array, signal-to-noise ratio, and an analysis of variance were...
