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% SiO₂are 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)
