Utrasonic topic: "Ultrasonic Deagglomeration"
Deagglomeration describes the process of breaking up or dispersing particles which have agglomerated, aggregated, or formed clusters. Interparticle forces can be classified into two groups: Adhesive forces such as van der Waals, electrostatic and magnetic attraction, mechanical interlocking and chemical bonds require no material bridge between the particles. Solid bridges, capillary bonding forces and immobile
liquid bridges are based on the formation of solid connections between particles.
Ultrasonic deagglomeration and dispersing is a powerful method to break particle agglomerates and aggregates into individual particles and results in uniformly dispersed suspensions. An important application field of ultrasonic dispersers is the dispersion of nanoparticles such as carbon nanotubes, silica, alumina, titanium dioxide or magnetite.
Acoustic cavitation, the working principle behind ultrasonic deagglomeration and milling, creates intense hydraulic shear forces, which overcome the interparticle bondings and promote deagglomeration of agglomerated particles to mono-dispersed nanoparticles.
