Statistical analysis of sonochemical synthesis of SAPO-34 nanocrystals using Taguchi experimental design

[Display omitted] ► Sonochemical synthesis of SAPO-34 nanocrystals. ► Using Taguchi experimental design (L9) for optimizing the experimental procedure. ► The significant effects of all the ultrasonic parameters on the response. SAPO-34 nanocrystals with high crystallinity were synthesized by means of sonochemical method. An L9 orthogonal array of the Taguchi method was implemented to investigate the effects of sonication conditions on the preparation of SAPO-34 with respect to crystallinity of the final product phase. The experimental data establish the favorable phase crystallinity which is improved by increasing the ultrasonic power and the sonication temperature. In the case of ultrasonic irradiation time, however, an initial increases in crystallinity from 5min to 15min is followed by a decrease in crystallinity for longer sonication time.
