Potential of liquid jets for preparation of micro and nano particles

摘要

The coaxial symmetrical water jets with sucked material particles are directed against each other in a small interaction chamber. Material particles are disintegrated into smaller ones in mutual collisions, in collisions with a high velocity opposite moving liquid and in consequence of the cavitation phenomena. The theory was prepared and first experiments were performed and analysed. The results are discussed in view of application of the opposite "abrasive" liquid jets for development of new materials both by softening of particles in a special medium and by a synthesis of jointly ground materials.
