Silica Sand, also known as industrial sand or quartz sand, is a high-purity sand composed primarily of silicon dioxide (SiO2) in the form of quartz. It is a hard, chemically inert material with a consistent grain shape and size, making it highly valuable in a wide range of industrial applications.
Key Characteristics: Common Uses: Composition: ≥ 95% SiO2 (can exceed 99% for high-purity grades) Color: White to light tan Grain Shape: Rounded or angular, depending on source and processing Grain Size: Varies by application (typically 0.1–2 mm)
Common Uses:
Glass Manufacturing: Essential raw material for flat glass, container glass, and fiberglass
Foundry Sand: Used in metal casting molds
Construction: Ingredient in concrete, mortar, and building materials
Filtration: Used in water and wastewater filtration systems
Hydraulic Fracturing (Fracking): Proppant to keep fractures open in oil and gas wells
Industrial Abrasives: For sandblasting and surface finishing
Ceramics and Refractories: As a filler or structural material
