What is Silica Sand? What is Silica Sand? - Definition, Properties, Applications, Types, and Pricing Silica Sand, also known as quartz sand, is a widely used mineral in various industries. It primarily consists of silicon dioxide (SiO₂) and is valued for its unique physical and chemical properties. Silica sand is extensively used in glassmaking, foundry casting, water filtration, paint production, and construction industries.Properties of Silica SandChemical Composition: High-purity silica (SiO₂) Hardness: Approximately 7 on the Mohs scale Color: White, colorless, yellow, brown, or gray Grain Size: Fine to coarse grains Specific Gravity: 2.65 g/cm³ Solubility: Insoluble in water and weak acidsSilica Sand Specifications TableFeature DetailsChemical Composition High-purity silica (SiO₂) with minor amounts of iron oxide (Fe₂O₃), alumina (Al₂O₃), titanium (TiO₂), and calcium (CaO)Hardness Around 7 on the Mohs scaleColor White, colorless, yellow, brown, or gray, depending on impuritiesGrain Size 0.1mm to...
