Abstract

High-power ultrasound was applied during the hydration of MgO fine powders in order to see the effect of ultrasound in a heterogeneous fluid where the dissolution of MgO particles and the precipitation of Mg(OH)2 are included. The results obtained showed that the irradiation of ultrasound fairly promotes the dissolution of MgO, which is the rate-determining step in the reaction, and that it promotes the nucleation of Mg(OH)2, which has resulted in the reduction of crystallite sizes of the Mg(OH)2 precipitated.
