N2  - The acid-used sol-gel synthesis of nano-sizedtitania (TiO2) powders has been studied systematically to optimizethe processing parameters by Taguchi method that control crystallite size. Inaddition, crystallite and particle size of TiO2 powders wereexamined by X-ray diffraction (XRD) and transmission electron microscopy (TEM).For this purpose, the amount of acid, reaction temperature and reaction timewere determined as control parameters. In order to achieve these objectives,Taguchi’s L9 orthogonal design (3 parameter, 3 level) was used forthe experiential design. Optimal synthesis conditions were described by use ofthe signal-to-noise (S/N) ratio which was calculated from crystallite size ofthe nano-sized TiO2 powders using "the-smaller-the-better"appoachment. Besides, analysis of variance (ANOVA) was utilised to accomplishthe statistical importance of the synthesis parameters. Experiments were fulfilledto verify the model at the chosen conditions and the particle size was determinedaccording to XRD analysis as 46.98 nm. Moreover, the actual size of the synthesisednano-sized TiO2 powders with the average size of 51.41 nm. Therefore,the Taguchi optimization method was an main tool in the optimisation of thenanosized TiO2 powders synthesis process with less experiential testsand slightly cost-efficient approachment.
