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.
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.
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 ...
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
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).
