Silica Sand
High-purity silica sand (Quartz Sand / Industrial Sand) with SiO₂ content up to 99.2%, Mohs hardness 7, for glass, foundry, construction, filtration, ceramics, and more.
Overview
Built for Industrial Buyer
Silica sand (also known as Quartz Sand or Industrial Sand) is a high-purity product primarily composed of silicon dioxide (SiO₂). It is characterized by its controlled grain sizing, high melting point, chemical inertness, and a Mohs hardness of 7. We supply superior quality silica sand processed to international standards in Glass Grade, Foundry Grade, and Construction Grade variants. The material is available in wet and dry forms with mesh sizes tailored to customer demand, and is exported globally from Gandhidham, Gujarat.
High SiO₂ content — up to 99.2% for glass grade
Mohs hardness 7 — sharp, durable, chemically stable grains
Multiple grades — Glass, Foundry (AFS 40–65), and Construction
Controlled grain size distribution available in various AFS numbers
Meets IS 2386 standards for construction applications
Available loose bulk, 50 kg PP bags, and 1 MT jumbo bags
