Fumed Silica is a notoriously difficult powder to disperse due to its extremely low density. As the powder is so fine, it tends to float on top of liquid surfaces and so it can be exceedingly difficult to wet out and processing often takes a long time. This also causes issues due to dusting. A degree of shear is also required to complete dispersion and obtain a full yield from fumed silica.

When choosing mixing equipment for this application, high shear mixing technology is far superior to conventional mixers and stirrers which simply are not up to the task.
The ‘how-to’ video from Silverson Machines demonstrates how the high shear action of a Silverson mixer draws the powder down into the workhead of the mixer so no powder is left to float on the surface. The powder and liquid are then vigorously mixed in the rotor/stator workhead before being expelled back into the mix, resulting in an agglomerate-free, stable viscosity solution in a fraction of the time taken with conventional methods.
