Mechanism of ultrasound strengthening preparation nanomaterials
2016
This paper will discuss strengthening mechanism of ultrasonic hydroxyapatite nm from each ultrasound parameters, such as: research ultrasonic power, intensity, frequency, etc., the findings concluded that ultrasound is through a liquid medium to a solution of molecules, ions action. When the ultrasound propagation in a liquid medium and the energy reaches a certain threshold, it will have a "cavitation" phenomenon. Thus, the formation of cavitation nuclei and growth has played a significant role in promoting, ultrafine, uniform nano-powders obtained provides a good foundation, it has been widely used in the preparation of nanometer powder.
