Silica Vardhman India (325 mesh)

Silica India Powder usually refers to finely ground silica (SiO₂) sourced or processed in India. It is made from naturally occurring silica-rich minerals that are crushed, washed, and milled into powder.

Main Raw Materials

1. Silicon dioxide (SiO₂)
The primary chemical component
Found naturally in quartz-rich rocks
Purity can range from ~95% to 99.9% depending on grade

2. Quartz
Most common source material
Hard, crystalline mineral composed of SiO₂
Used for high-purity silica powder

3. Quartzite
Metamorphic rock made mostly of quartz
Used for industrial-grade silica

4. Silica sand
Naturally occurring granular silica
Mined, washed, and ground into powder
Typical Composition (Industrial Grade)

SiO₂: 95–99%
Small traces of:
Iron oxide (Fe₂O₃)
Alumina (Al₂O₃)
Calcium oxide (CaO)
Magnesium oxide (MgO)

Higher-purity grades (for glass, electronics, or specialty ceramics) undergo additional processing to remove impurities.
