Main Article Content
Abstract
The technique for producing magnetite powders by chemical and sonochemical methods is described. Intensive mixing accompanying ultrasonic cavitation and the formation of a large number of nucleuses allows to conduct the reaction in a short time. This contributes to the monodispersity of the obtained product. The dispersion and morphology of magnetite powders are investigated. It is shown that the ultrasound effect allows to obtain round-shaped magnetite powders with an average particle size of ~ 25 nm.
