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 Sand Chemical 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 acids Silica Sand Specifications Table Feature Details Chemical 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 scale Color White, colorless, yellow, brown, or gray, depending on impurities Grain Size 0.1mm to...
