  • Process for the production of precipitated silica

    Jan 16, 1996The precipitated silica has a BET surface area of 10-130 m 2 /g, a CTAB surface area of 10-70 m 2 /g, an average particle diameter of 5-20 μm, a Cu abrasion value in a 10% glycerol dispersion of 4-50 mg, and thickening behavior in a CMC solution (20% dispersion) of 300-3500 mPa s.

  • PRECIPITATED SILICA

    PRECIPITATED SILICA Precipitated silica is a silica (SiO 2) produced by precipitation from a solution containing silicate salts. 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.

  • Precipitated Silica

    Pyrogrenic silica's and precipitated silica's are essentially not microporous. An exception is made for those silica's prepared by the Stber process. These silica's would seem to be ultramicroporous with pores too small to allow nitrogen molecules to penetrate the porosity.

  • Simulation of iron oxide/silica precipitation in the

    Conversely, where silica is allowed to polymerise prior to the iron precipitation reaction, a greater proportion of silica is removed from the solution. As these effects are key to an effective precipitation stage in the process, the influence of silica polymerisation must figure in considerations when handling high-silicate concentrates.

  • Silica thickener introduction

    Hydrophobic (water-hating) silica is made by reacting the silica with silanes and silazenes. The hydrophobic silica is ideal when used as a thickener for a grease that is required to prevent water ingress or to give a grease excellent water washout resistance.
