Brisil has developed a technology to produce highly dispersible silica and precipitated silica from rice husk ash. The technology is a zero waste chemical process which uses rice husk ash as feed and produces precipitated silica and other byproducts. The technology can extract up to 70% silica .
Solubility of amorphous silica At the reservoir, the SiO 2 content is in a equilibrium state with quartz (Brown, 2011). However, precipitated silica at the surface is normally in an amorphous silica form. The solubility of amorphous silica with temperature in pure water has been measured (Fournier and Rowe, 1966, op. cit. Brown 2011).
and a new filler of silicamodified PCC obtained by the solgel method are presented. This new filler proved already to be advantageous at lab scale and its performance is now evaluated at a pilot scale. Its application in a pilot paper machine led to results better than those obtained at lab scale.

Controlling the properties of precipitated silica (PS) synthesized by acidizing sodium silicate solution is a significant challenge. Here, we report the effect of gelation on the BET surface area and pore volume of the PS produced at the pilot scale.
Precipitated Silica is produced on commercial scale from aqueous alkali metal silicate solutions (, water glass) and acids (, sulfuric acid), usually via precipitation carried out in batch mode. It is worth to highlight that, depending on the manufacturing process, Precipitated Silica may be produced with different physical and
Fumed silica and Precipitated silica. Fumed silica and Precipitated silica. Both of fumed silica and precipitated silica are silicas, or silica dioxide(SiO2). Their cost different is mainly due to different production technology and raw materials. Fumed silica and precipitated silica are for different applications. As a result of their ...

these synthetic silica, and after a time it became necessary to produce them on an industrial scale. Synthetic silica are classified in two groups, depending on the manufacturing process used: fumed or thermally produced silica and silicate that are produced by means of the wet process. Silicate such as SIPERNAT® 820 A are also produced by
Silica gels are used for a range of applications and can be produced from Geo40''s colloidal silica. Geo40 is working on a range of silica gel products made from environmentally friendly geothermal silica. In Japan, Geo40 was part of a consortium, funded by the Japanese government, to demonstrate the Geo40 technology.
