Silica Sand

• Silica sand is valued for several useful properties. It owns high melting point and low thermal expansion coefficient, which makes it a good choice for applications that involve high-temperature exposures.
• Glass
• Silica sand is a primary component in the manufacturing of glass. It is a very important raw material for standard and special glasses. The chemical purity of silica sand is the principal determinant of strength, colour and clarity.

• It is used to produce flat glass for building and automotive uses and for container glass that stores food and beverages. It reinforces glass fibres and required for the production of fibreglass insulation.

• It is applied in speciality glasses that include test tubes, scientific tools, television and CRT monitors, and also in incandescent and fluorescent lamps.

• Calcium silicate bricks:

• For manufacturing calcium silicate bricks, silica sand is mixed with high calcium lime with a sand to lime ratio of 10 or 20. These bricks contain good regularity, smooth faces, and sharp corners with a wide variety of strength.

• The durability of calcium silicate bricks is similar to concrete and is not resistant to sulphur- containing environments.

• Metal Casting & Production

• Silica sand is an essential part of the production of steel, ferrous and non-ferrous foundry industries for de-oxidation and grain refinement. For obtaining desired internal or external shapes, metal parts are cast in silica sand.

• It is a preferred choice for castings that involve cast iron, steel, titanium and also used to clean the casting surfaces.

• Construction

• It is the primary component in a variety of building and construction products. For improved durability and structural integrity, whole grain silica is used in flooring, mortars, specialty cement, roofing shingles, asphalt mixtures, skid-resistant surfaces and in other industrial materials.

• It performs as a functional extender to add durability, anti-corrosion and weathering properties in sealants, caulks, epoxy-based compounds
