超细二氧化硅粉体的制备及应用已成为科研的热门领域，然而制备的微粉颗粒表

The preparation and application of ultra-fine silica powder have become a hot field of scientific research, however, the prepared micro-powder particles show unevenness and are easy to agglomerate. In view of this, ultrasonic waves are added to the experiment to show many excellent physical and chemical properties, which not only has a short time, but also provides a new and very special reaction environment for chemical reactions that are usually difficult or impossible to achieve.

The preparation and application of ultrafine silica powder has become a popular field in scientific research, however, the prepared micropowder particles show uneven ness and are easy to reunite. In view of this paper in the experiment to add ultrasonic, thus showing a lot of excellent physical and chemical properties, not only short time, but also for the usual difficult to achieve or can not achieve a chemical reaction environment provides a new very special reaction environment.

The preparation and application of ultra-fine silica powder has become a hot field of scientific research. However, the prepared particles are uneven and easy to agglomerate. In view of this, this paper adds ultrasound to the experiment, which shows many excellent physical and chemical properties. It not only has a short time, but also provides a new and very special reaction environment for the chemical reactions that are difficult or impossible to realize at ordinary times.<br>
