about

Silica


Silica (SiO2) is the term used to describe a group of minerals composed of oxygen and silicon. Whilst it is the world’s second most abundant mineral, products containing at least 98% SiO2 are needed for industrial use.


At Sibelco, we produce the
crystalline forms
of silica – quartz and cristobalite – as both
sands
and
flours
. As a hard, chemically inert mineral with a high melting point, silica delivers a range of benefits across multiple applications.

We offer a wide range of silica products in various formats, including:

  • Dry ( incl. calibrated, resin-coated & coloured)
  • Wet (incl. calibrated)
  • Low iron
  • Flours ( incl. low iron, fused and micronised)
  • Calcined sands & flours
  • Crude
  • Gravel
