Features Of Micro Silica (Silica Fume) Micro Silica also known as Silica fume. It is a by product of producing silicon metal or ferrosilicon alloys in smelter using electric arc furnaces. It is a grey coloured powder, pozzolanic in nature. Applications Concrete Industry Refractory Rubber Industry Anti caking agent Pellet Binder
Fumed silica serves as a universal thickening agent and an anticaking agent (free-flow agent) in powders. Like silica gel, it serves as a desiccant. It is used in cosmetics for its light-diffusing properties. It is used as a light abrasive, in products like toothpaste.

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.
Introduction Fumed silica is hydrophilic fumed silica(silicon dioxide). It is high purity and fluffy powder with typical specific surface area of 150g, 200g, 300g, 380g. Furthermore, it is characterized by an x-ray amorphous structure. Positive effects: Optimum adjustment of rheology during processing Reinforcement of silicone elastomers Thickening of non-polar liquids Free-flow of foodstuffs and industrial powders High chemical purity Excellent insulation properties, even at high temperatures Conversion of liquids to powders, e.G.

Hydrophilic Fumed Silica A.Characteristic: It is a white and colloidal micro-particle with its primary micro-particle from 5-40 nm and has obvious properties such as thixotropy, reinforcing, thickening and filling etc. and is insoluble in all kinds of solvents and liquids except hydrofluoric acid and concentrated bases. It is used widely in silicon rubber, construction sealant, coating, electron and electric, aerospace, medicine and medical material, resin processing, printing ink, pesticide and other industries. F-150: used widely in silicone acid rubber, sulfurized silicone rubber in ambient temperature (low water content), silicone neutral rubber. F-200: used widely in sealing ring, sealing gasket, petroleum pipeline, insulator, tablet powdered preparation, artificial viscera, infusion tube, latex nipple and high quality oil ink. F-380: used widely in reinforcing agent for silicone rubber, medical silicone rubber for transparent artificial organs and artificial heart etc. Packing: packed with multi-layer paper plastic compound bag with net weight of 5 kg or 10 kg, or packed by whole plastic seal for users having special demand on water content. 10kg per bag
It is sometimes confused with fumed silica. The production process, particle characteristics and fields of application of fumed silica is however different as compared to silica fume.

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.
