Grinding, deagglomeration and dispersion to small, relativley uniform particle size.
Ultrasonic Dispersing and Deagglomeration.
Ultrasonic Deagglomeration of Nanomaterials.
Ultrasonic catalyst preparation can cause changes in crystallization behavior, dispersion/ deagglomeration and surface properties.
Deagglomeration and particle size reduction e.g. to obtain single-dispersed particles.
Ultrasound is an effective means for the dispersion and emulsifying, deagglomeration and milling of such components in coatings.
The dispersing and deagglomeration of solids into liquids is an important application of ultrasonic devices.
It is designed to work in clusters of four or more units, for large volume processing, such as homogenizing, dispersing and deagglomeration.
Mixing, Dispersing and Deagglomeration as well as Deaeration by powerful ultrasonic forces.
Companies, like Panadur(Germany) use Hielscher ultrasonic devices for the dispersing and deagglomeration of nanomaterials in in-mould coatings.
The higher the grade of deagglomeration, the better the extraordinary material properties are exploited.
Thereby, high-power/ low-frequency ultrasound can be used for the processing of liquids such as mixing, emulsifying, dispersing and deagglomeration, or milling.
By ultrasonic dispersing and deagglomeration the chemical reaction can proceed much more completely.
Watts ultrasonic power- The UP400S(400W, 24kHz) is a powerful and reliable ultrasonic device for the sonication of larger samples in the lab. Typical application include: Homogenization, deagglomeration, lysis and cell disintegration, protein extraction and the emulsification of….
As already described, the deagglomeration and the even particle size distribution in the medium are essentials for the successful exploitation of nanodiamonds' unique characteristics.

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.
When these extreme forces, which are generated during the collapse oft he cavitation bubbles, expand in the sonicated medium, particles and droplets are affected- resulting in interparticle collision so that the solid shatter. Thereby, particle size reduction such as milling, deagglomeration, and dispersion are achieved. The particles can be diminuted to submicron- and nano-size.
Ultrasonication is a very effective means for the mixing, dispersing and deagglomeration. The picture below shows a typical result of ultrasonic dispersing of fumed silica in water.
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.
The picture to right(Click for larger view!) shows the particle size distribution curves for the deagglomeration of Degussa anatase titanium dioxide by ultrasonication. The narrow shape of the curve after sonication is a typical feature of ultrasonic processing.
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.
It is decisive, that water, cement and admixtures are evenly dispersed and distributed down to a fine scale and that agglomerates are sufficiently dispersed. Insufficient dispersing or deagglomeration results in inferior concrete properties. Due to the low water content and the high dosage of admixtures, the mixing of self-compacting concrete(SCC) and ultra high strength concrete(UHPC) requires a longer mixing time or a more effective mixing technology.
Sonofragmentation describes the breakage of particles into nano-sized fragments by high power ultrasound. In contrast to the common ultrasonic deagglomeration and milling- where particles are mainly grinded and separated by inter-particle collision-, sono-fragementation is distinguished by the direct interaction between particle and shock wave. High power/ low frequency ultrasound creates cavitation and thereby intense shear forces in liquids. The extreme conditions of cavitational bubble collapse and interparticular collision grind particles to very fine size material.
