ball milling ultrasonic

Ultrasonic Wet-Milling and Micro-Grinding Ultrasonication is an efficient means for the wet-milling and micro-grinding of as colloid mills (e.g. ball mills bead mills) disc mills jet mills rotor-stator mixers

Research has shown that ultrasonic milling can be successfully used for fabrication of thermoelectric nanoparticles and has the potential to manipulate the surfaces of the particles. Ultrasonically milled particles (e.g. Bi 2 Te 3-based alloy) showed a significant size reduction and fabricated nano-particles with less than 10µm.
