Sol—Gel Processing of Silica Advances in Chemistry (ACS

The sol—gel process for preparing silica and silicates from metal alkoxide precursors is reviewed and compared to the processing of aqueous silicates as described by Iler. Sol—gel processing combines control of composition and microstructure at the molecular level with the ability to shape material in bulk, powder, fiber, and thin-film form. In sol—gel processing of metal alkoxides

Silica an overview ScienceDirect Topics

Processing of silica of specific quality yields several types of specialty silicates. These include: (1) colloidal, (2) fumed, (3) fused, (4) high-purity ground silica, (5) silica gel, and (6) precipitated silica. Colloidal silica is mainly used as a high-temperature binder for silicon wafer, polishing, and precipitated silica.

What is Silica? Eurosil

Silica deposits are normally exploited by quarrying and the material extracted may undergo considerable processing before sale. The objectives of processing are to clean the quartz grains and increase the percentage of silica present, to produce the optimum size distribution of product depending upon end use and to reduce the amount of

Stöber process Wikipedia

The Stöber process is a sol-gel approach to preparing monodisperse (uniform) spherical silica (SiO 2) materials that was developed by a team led by Werner Stöber and reported in 1968. The process, an evolution and extension of research described in Gerhard Kolbe's 1956 Ph.D. dissertation, was an innovative discovery that still has wide applications more than 50 years later.
