Abstract

In this paper, we focused on the evolution of transient cavitation activity during the sonochemical treatment of magnesium aqueous suspensions. We have investigated the non-linear behavior of the cavitation activity related to the hydrogen released in the reaction of magnesium with water. Ultrasound modifies magnesium particles leading to the formation of nanostructured Mg(OH)2 phase (brucite) resulting in the chemical and sonochemical impacts on magnesium.
