Fumed silica, also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles.
It is mainly used in Coatings, paints, Sealant, Adhesive, Pigment, Ink, unsaturated polyester resin, etc, because of its unusual particle characteristics, enormous surface areas, high purity, aggregated structure and low bulk density. Packing: Vacuum packing, with multiple layer Kraft paper, 10KG/bag.

Micro Silica Sand: Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica. Applications : Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste. Advantages : Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.
Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications. Silica sand is used in industrial processing, to make glass, as fill, and to create molds and castings. Silica sand is produced by crushing sand stone or quartzite of open texture, and washing and garding it to yield requisite grain distribution. Silica flour is produced by crushing grinding and washing the high grade quartz, quartzite rocks or from white silica sand. Salient Features Silica Sandstone is moisture free, fritable & hard. Grain size of the particles is variable. Friable & mainly brown to grey in colour.
