Silica (SiO2) is a multi-functional ceramic material that is being used in various industries to improve surfaces and mechanical properties of diverse materials. It is used as a filler, performance additive, rheological modifier or processing aid in many product formulations, such as paints & coatings, plastics, synthetic rubber, adhesives, sealants, or insulation materials. In particular silica fume (amorphous silicon dioxide) or micro silica is being added to concrete in order to improve the concrete strength and durability. Silica fume is also being used in refractory concretes to reduce porosity and to enhance strength by improved particle packing.
Ultrasonic processing has been proven to be more effective in the dispersing of silica than other high-shear mixing methods. The picture below shows a typical result of ultrasonic dispersing of fumed silica in water.
