First of all, the propagation of ultrasound needs to be based on the medium.
The propagation of ultrasonic wave in medium has alternating cycle of positive and negative pressure. The medium is squeezed and pulled by the positive and negative pressure of colloid.
When the ultrasonic wave acts on the liquid medium, the distance between molecules in the negative pressure region will exceed the critical molecular distance of the liquid medium. The liquid medium will break and form microbubbles, which will become cavitation.
The bubble can be redissolved in the gas, it can also float up and disappear, or it may collapse from the resonance phase of the ultrasonic field. It produces local high temperature and high pressure, and produce huge impact force and micro jet. Under the action of nano particle, the surface energy can be weakened, thus achieving the dispersion of nano particle.

Advantages:
1. Comparing with the traditional mixing and ball milling process, the operation cost of the ultrasonic production capacity is greatly reduced. Especially suitable for industrial production.
2. For liquid with liquid mixing, it could speed up the chemical reaction and reduce the amount of additives. The fully mixed solution should not be layered for a long time.
3. For the solid with liquid mixture, the easily agglomerated nanoparticles could be opened in a short time, and the dispersed ultrafine particles are not easily to gather again.
