The dispersion and depolymerization of ultrasonic wave are the result of ultrasonic cavitation.
When the liquid is treated with high intensity ultrasonic wave, the propagation of sound wave into the liquid medium will lead to alternating cycle of high pressure (compression) and low pressure (reflection), depending on the frequency. In the process of low-pressure circulation, high-intensity ultrasound will produce small vacuum bubbles or voids in the liquid.
When the bubble reaches a size that cannot absorb energy, it will collapse violently in the high pressure cycle. This phenomenon is called cavitation. During the burst, a very high temperature (about 5000K) and pressure (about 2000atm) were achieved locally.
The breakup of cavitation bubbles also leads to the liquid jet velocity up to 280m / s.
The cavitation force produced by cavitation bubbles in the process of instantaneous collapse is very important, and it is known that it can cause many chemical and physical effects [1], such as the formation of free radicals due to the cracking of solvent molecules, the increase of chemical reaction rate and mechanical effects (such as corrosion).
Solid surface or pitting, dispersion of polymer powder in solution and particle breakage.

Ultrasonic homogenizing for Nano materials attracted the attention of scientists, researchers and engineers of almost any branches as nano-sized particles show unique characteristics. Their physical properties such as optical and magnetic properties, specific heats, melting points, and surface reactivity offer high potentials for material with extraordinary strengths. But the smaller particles, the more difficult becomes treatment. Ultrasonic homogenizer is often the best method to effect nano particles effectively. Mostly, high power ultrasonic homogenizer are the only efficient way to achieve the desired milling and dispersing results of nano particles such as nanotubes, graphene, metal oxides etc.
The ultrasonic homogenizing system effects on biological and microbiological systems are manifold: Dispersing & Homogenizing, cell and tissue lysis (e.g. bacteria, yeast, viruses, algae…) & extraction of intracellular materials such as proteins, ribosomes, RNA, lipids, peptides…, plant cell transformation.
