Granular Quartz
High-purity, angular quartz granules. Ideal for epoxy flooring, decorative applications and composite fillers; XRF measurements show SiO₂ ≈ 99.8% purity.

What is Granular Quartz?
Granular quartz is a high-purity quartz granule with an angular grain structure; it is particularly preferred in epoxy flooring, decorative applications and composite fillers. With a SiO₂ content of around 99.8% in XRF measurements, our product offers high whiteness and chemical purity thanks to its low iron oxide content. Processed at our facilities in the Trakya region, the quartz is classified with a controlled grain distribution.
Granular quartz is a high-purity industrial mineral made up of visibly angular grains, obtained by washing and classifying quartz ore. The typical SiO₂ content is ≈99.8% and the Fe₂O₃ content is ≈0.013–0.019%; this low iron content makes it ideal for applications that call for whiteness and colour stability. With a Mohs hardness of 7 and a density of 2.65 g/cm³, the product delivers long service life in flooring systems that require mechanical strength and abrasion resistance. It can be supplied in the 0.5–2 mm range, in different fractions as required.

Where is it used?
In epoxy and polyurethane floor coatings, its angular grain structure provides high adhesion, mechanical strength and slip resistance.
In composite materials and special renders, it acts as a filler aggregate that adds strength and surface quality.
Used as a granule that provides homogeneous colour and hardness in decorative mortars and special building chemicals.
Featured as an aesthetic and durable aggregate in mosaic, terrazzo and decorative surfaces.
High-purity (SiO₂ ≈ 99.8%) angular quartz granules are used as an SiO₂ source for clear, high-quality results in speciality glass and composite surface production.

What is the difference between granular quartz and silica sand?
Granular quartz has a higher purity (SiO₂ ≈ 99.8%) and an angular grain structure; it is optimised for epoxy and decorative applications. Silica sand, on the other hand, offers a wider range of fractions and 96.3% SiO₂ for general industrial use.
Which grain size is suitable for epoxy flooring?
Angular quartz granules in the 0.4–1.2 mm range are generally preferred for epoxy flooring applications; the final choice is made according to the system thickness and the desired surface texture.
What is the SiO₂ purity of granular quartz?
The typical SiO₂ content in XRF measurements is around 99.8%. This high purity is suitable for applications that require whiteness and chemical stability.
