Silica Sand

Silica Sand is a granular material composed primarily of silicon dioxide (SiO₂), derived from natural quartz deposits. With a purity level of SiO₂ = 99.5%, this grade is classified as high-purity silica sand, suitable for demanding industrial applications such as glass manufacturing, foundry casting, and chemical processing.

Chemical Composition (Typical Laboratory Result)

Component

SiO₂ (Silicon Dioxide) = 99.5 %
Fe₂O₃ (Iron Oxide) = ≤ 0.03 % (typical low level)
Al₂O₃ (Aluminum Oxide) = ≤ 0.2 %
CaO (Calcium Oxide) = ≤ 0.05 %
MgO (Magnesium Oxide) = ≤ 0.05 %
Loss on Ignition (LOI) = ≤ 0.1 %
Moisture Content = ≤ 2 %

The extremely high SiO₂ content ensures chemical stability, thermal resistance, and optical clarity for industrial use.
