Dispersion for Alumina

When ultrasonic waves act on liquids, a large number of small bubbles can be generated. One reason is that partial tensile stress occurs in the liquid to form a negative pressure. The decrease in pressure makes the gas originally dissolved in the liquid supersaturate and escape from the liquid and become small bubbles. Another reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation.

Introduction：
In the precipitation method, the mechanical vibration of ultrasonic waves is mainly used to influence the kinetics of the precipitation formation process, and to control the particle size by the shearing and breaking mechanism of ultrasonic waves. Ultrasonic waves can accelerate the formation of crystals and make the crystal size distribution uniform.
Advantage： Uniform dispersion effect, high cost performance
