This work considers the deagglomeration and wettability of particles by metal melt and proposes a mechanism of particle agglomerate dispersion by ultrasonic cavitation. The main dependences connecting the processing time and intensity with the physical and chemical properties of particles and the melt as well as acoustic parameters are obtained. For the first time found that melt during ultrasonic treatment, inclusive the particles agglomerates proportional to melt viscosity and the size of the agglomerates. It has been established that time ultrasonic treatment melt containing the particles agglomerates is proportional to melt viscosity and the size of the agglomerates. The required time for successful melt infiltration in the agglomerates, wettability and their introduction into the melt takes ten minutes. The suggested equation allows estimating the intensity of ultrasonic radiation, required to destroy the agglomerates of particles in the melt. It was found that intensity of the ultrasound must be inversely proportional to the radius of the agglomerates. The theoretical results are confirmed by comparing with experimental dates.
