Jan 03, 2017· Precipitated silica is produced using the conventional wet chemistry process as well as the new Spherilex™ silica wet chemistry process developed by Huber Engineered Materials. The new process produces material with a unique spherical particle morphology, providing nontraditional silica benefits in coatings.
Jun 01, 2017· Precipitated silica commonly known as silica, also known as hydrated silicic acid, light silica, chemical expression is generally written as mSiO2 · nH2O, th
Mar 17, 2020· Precipitated silica, an amorphous form of silica (silicon dioxide), is a critical ingredient used in many applications worldwide. These materials can be added to products during the manufacturing process to provide key performance benefits.
Precipitated silica and colloidal silica are produced in the process shown in Figure 4.37.Since the original raw material is silicic acid sodium, relatively inexpensive SiO 2 particles are obtained. Precipitated silica ((a) in the figure) is not a single particle but rather a body of several precipitated
Process for the production of precipitated silica from olivine including the following steps: providing olivine particles with a particle size preferably below 1 mm in diameter, preferably mixing olivine and water to form an olivine/water slurry, mixing the olivine/water slurry with hydrochloric acid (HCl), preferably at a Concentration at 18 wt % or above, and at a temperature preferably
Production Process The production of precipitated silica starts with the reaction of an alkaline silicate solution with a mineral acid. Sulfuric acid and sodium silicate solutions are added simultaneously with agitation to water. Precipitation is carried out under alkaline conditions. The cho of agitation, duration of precipitation, the
YTI has modified the process to produce high purity precipitated silica directly from a range of low cost feed stocks. As a result of the successful testing of its technology, YTI has created Yava Silica LLC to develop commercial precipitated silica production facilities incorporating the new process.

The process was extensively developed by Martin and Synge (ca. 1941-1948) who partitioned amino acid derivatives between chloroform and water using precipitated silica as support for the aqueous phase. The preparations of silica were again very variable and it was difficult to prevent adsorption which interfered with the expected behavior of
