Silica sand (also called industrial sand) is a high-purity form of sand composed mainly of silicon dioxide (SiO₂) in the form of quartz.
It is widely used across construction, glass, foundry, filtration, and chemical industries due to its hardness, chemical purity, and heat resistance.

Uses of Silica Sand

1. Glass Manufacturing: Container glass, Flat glass (windows), Fiberglass, Solar panel glass

2. Foundry & Casting Industry: Metal casting molds, Cores, Steel, iron, and non-ferrous casting

3. Construction & Building Materials: Concrete (improves strength and density), Mortar mixes, Plaster, Flooring compounds, Paver blocks, Ready-mix concrete

4. Filtration: Drinking water filtration, Swimming pool filters, Wastewater treatment, Industrial filtration systems

5. Ceramics & Refractories: Tiles, Sanitaryware, Porcelain, Furnace linings

6. Chemicals & Industrial Applications: Paints and coatings, Adhesives & sealants, Rubber & plastics fillers, Abrasives

7. Oil & Gas Industry: As frac sand in hydraulic fracturing (propant).
