Quartz powder is very finely ground quartz (silicon dioxide, SiO₂). It is a hard, angular powder that is widely used in industry and arts as a filler.
The material is known for its strength and is used for, among other things:
Resins:
As a filler in polyester and epoxy resins to reduce shrinkage, increase volume, and improve wear resistance.
Construction and ceramics:
As an aggregate in concrete, mortar, silicate products, and ceramics.
Art and paint:
As a base in specialty paints or as an additive in casting compounds.
Chemistry
> 99.7% SiO2, down to 0.007% Fe2O3
Particle size
various types with D50 value ranging from 35 microns down to 2 microns.
