Research and Development. Precipitated silica, a form of synthetic amorphous silicon dioxide, is derived from quartz sand, a crystalline form of silicon dioxide. The physical properties of precipitated silica can be manipulated during the manufacturing process to deliver products with a wide range of performance-enhancing features engineered for many different end-use …

Precipitated silica or Precipitated SiO2 is an amorphous form of silica. In appearance, it is a white, powdery material. Precipitated silica is manufactured by the precipitation from a solution with silicate salts. The three primary classes of amorphous silica are pyrogenic silica, precipitated silica, and silica gel.

Precipitated silica (SiO 2) is industrially produced by mixing a silicate solution with acid in a semi‐batch process. Polycondensation of monomeric silica leads to the formation of particles which aggregate and eventually form a particulate gel. However, this is instantly fragmented by the mechanical energy input caused by the stirrer.

While the average density of silanols in amorphous silica is typically ~ 4.8 OH/nm 2, their density in various silicas differs significantly as follows: precipitated silica (~ 8.0 OH/nm 2) ≫ colloidal silica (~ 5.0 OH/nm 2) > microporous silica (4.6–4.9 OH/nm 2) > mesoporous silica (4.0–4.6 OH/nm 2) > silica gels (4.3–6.7 OH/nm 2) [25] ≫ commercial fumed silica (~ 2.0 OH/nm 2).

Hydrophilic fumed silica (FS) and precipitated silica (PS) powders were suspended in mineral oil; increasing the silica volume fraction (φ in the suspension led to the formation of sol, pre-gel, and gel states. Gelation took place at lower φ values in the FS than the PS suspension because of the lower silanol density on the FS surface. The shear stresses …
