Information profile @ a Glance
- Amorphous silica, silica gel, is produced by the acidification of
solutions of sodium silicate to produce a gelatinous precipitate that is
then washed and then dehydrated to produce colorless micro porous silica
- The Rice Hull contain 18-20% high purity amorphous Silica
- One pound of Rice Hulls contains same energy as one pound of Coal
- Colloidal silica is composed of the same substance (silicon dioxide)
as quartz sand but it has an amorphous (random) rather than a
crystalline structure
- Silicon dioxide (SiO2)(synthetic amorphous silica) :
Functions as a high temperature binder in refractories and ceramics ;
Used as a binder in the investment casting process (lost wax process)
;Polishes silicon and semiconductor wafers to a mirror-like finish ;
Helps to clarify and improve the quality of wines, juices and beer
- Diatomite (amorphous silica) is open-pit mined in the United States
and used to produce cristobalite
- Amorphous silica is generally less toxic than crystalline silica.
Since it has greater water solubility, it is cleared more rapidly from
the body. Effects observed after inhalation of amorphous silica were
milder than those observed for crystalline silica
- Amorphous silica may be added to food as an anti-caking or
anti-foaming agent or to pharmaceuticals as an excipient
- Fused amorphous silica or quartz (minimum 99.8% SiO2) in the form of
ingots, rods, tubes and powder are required for the chemical and
electronic industries
- The production of fumed amorphous silica from the hydrolysis of
silicon tetrachloride2 in a flame of hydrogen and oxygen is for use in
rubbers; as a
thickening agent in inks, paints, cosmetics, etc.; for use in polyester;
and in specialty coatings such as powder coatings
- The Amorphous Silica appears as white free flowing powder. It is
highly efficient anti-blocking aid for plastic films. It also provides
slip improvement. Due to its high purity and low hardness its
abrasiveness is negligible. It's no sedimentation easy adding and
well-dispersed features make this product enjoy the application fields
like: Food packing films ,Furniture coatings , Decorative paint , Other
general industrial coatings
