Information @ a Glance

  • Gels are a very efficient media for growing macromolecular crystals. Silica gels in particular have the advantage in that they are stable, usable over a wide range of temperature (0 - 60°C), and are compatible with a wide variety
    of precipitants and additives used for crystal growth.
  • Silica gel is a granular, porous form of silica made synthetically from sodium silicate.
  • Silica gel is most commonly encountered in everyday life as beads packed in a semi-permeable plastic.
  • A solution of sodium silicate is acidified to produce a gelatinous precipitate that is washed then dehydrated to produce colorless silica gel.
  • Silica gels can be produced from different raw materials. However, the synthesis from mineral acids, e.g. sulfuric acid, and aqueous sodium silicate is the only industrial relevant process today.
  • Aminopropyl silica gel was prepared from porous silica gel and was used as a solid support for immunoadsorbent in the purification of anti-glycolipid antibodies.
  • Silica gel may also be used to keep the relative humidity inside a high frequency radio or satellite transmission system waveguide as low as possible.
  • Silica gel is also used to dry the air in industrial compressed air systems. Air from the compressor discharge flows through a bed of silica gel beads.
  • Silica gel is sometimes used as a preservation tool to control relative humidity in museum and library exhibitions and storage.
  • Silica gel is applied to aluminum, glass, or plastic sheets for thin layer chromatography.
  • Silica gel is also used as cat litter, by itself or in combination with more traditional materials, such as clays including bentonite. It is trackless and virtually odorless, albeit expensive.
  • The sol-gel technology is believed to be an energy- and resource-saving process. At present, three directions of the sol-gel technology are employed to produce silica glasses suitable for optical applications.
  • Modern silica gel technology enables the production of highly pure gels that are composed of nearly 100% SiO2 with tailor-made pore systems and
    surface properties.
  • There is a patent for An improved and rapid process for purifying a silica hydrogel of soluble contaminants which comprises reducing the hydrogel to a controlled particle size range and thereafter treating the sized hydrogel in a continuous three-step operation. Treatment involves first dewatering a hydrogel slurry, washing the resulting hydrogel with acidified water, followed by washing with ammoniated water. All treatment steps are carried out on a moving belt maintained under a vacuum
