The effect of different approaches to the mixing of precursors (different durations of agitation with a magnetic stirrer, ultrasonic treatment of a precursor suspension) on the time required for the subsequent crystallization of SAPO-11 has been studied. Ultrasonic treatment reduces the duration of hydrothermal synthesis from 24 to 1 h and the overall time of preparation of SAPO-11 from 27 to 3 h. © 2019, Pleiades Publishing, Ltd.
