High purity fused silica particles are made by heating relatively low density silica flour in a high temperature flame. The silica flour feed rate, flame temperature, and collection zone temperature are adjusted to produce an aggregate of surface-bonded fused silica particles. The aggregate is shaped like a honeycomb and can be ground autogenously without introducing impurities into the final ...

Dispersion of Fumed Silica

As the powder is extremely fine it poses real problems due to dusting. Long processing times are required to fully disperse the powder once it is wetted out. Low shear mixing devices are generally unsuitable for dispersing fumed silica. While the powder may be wetted out, the lack of high shear mixing results in poor yield of thickening effect.

Powder Processing

Powder processing is the most commonly used technique for producing ceramic nanocomposites. As discussed in previous sections, this technique resulted in very good dispersions of nanoparticles in the ceramic matrix although not so good results were obtained for CNTs due to the complex processing steps required for de-agglomeration of CNTs.

How to Eliminate Electrostatic Charging of Powder ...

Powder processing operations can generate vast quantities of electrostatic charge via the movement of powder. The standard method of charging on powder processing operations is due to tribo-electrification, which is basically the contact and separation of the powder with processing equipment, the powder itself, or other factors that can cause charging, like surface contaminants.
