The expansion has increased the production capacity of the surfacemodified colloidal silica at the companys Bohus site in Sweden. In February 2019, W. R. Grace amp; Co. started the construction of a novel colloidal silica plant at the companys leading manufacturing and Ramp;D center in Worms, Germany.

Jun 23, 2020#0183;#32;W. R. Grace amp; Co. (Columbia, Md.) announced the opening of its new 8,200 squaremeter colloidal silica plant at its European flagship manufacturing and Ramp;D center in Worms, Germany. The facility doubles the worldwide production capacity of Ludox, Graces leading colloidal silica product, and significantly enhances Graces responsiveness to customers in Europe, the Middle East and
The present invention provides dense silica particles with less metal impurities. Specifically, the present invention relates to a colloidal silica obtained by using an alkyl silicate as a raw material, wherein a sample containing 1 wt% of polydimethylsilane as an internal standard for the colloidal silica is used as a solid 29 SiCP / MAS Wherein the peak area value determined by a
Colloidal silica is used in many applications including catalysis, pharmaceuticals, and coatings. Although naturally formed silica materials are widely available, they are often in forms that are difficult to process or are even harmful to health. Therefore, uniform colloidal silicas are generally manufactured using synthetic chemical processes. While established high temperature gaseous
#0183;#32;Known methods for the production of colloidal silica ( via sodium silicate) are generally only economically viable where the initial concentration of the silica solution is from 25 m %. The present invention makes use of a novel source of silica colloids and takes the silica concentration from a comparatively low silica concentration to 25 m % in an economically viable manner.
Colloidal silica is silica particles that are suspended in a liquid. The liquid is denser than water and has been stabilized electrostatically to allow the particles to stay suspended in the solution. The silica particles are also very small and do not have a large density. The range has to be approximately from thirty to a hundred nanometers.

Such a colloidal silica has a feature in which, with respect to a sample prepared by adding, as an internal standard, 1 wt. % of polydimethylsilane to a dried product of the colloidal silica, a peak area value calculated using a formula of a colloidal silica peak area/a polydimethylsilane peak area is 15 or less, the peak areas being determined by measuring a solidstate 29 SiCP/MASNMR
