High Purity Silica Sand

Best Sand’s high-purity silica sand and gravel are widely used in the foundry industry. The sub-rounded grain shape is proven to reduce expansion defects in cores and molds of all casting types. Furthermore, the high silica content allows Best Sand to be used among steel foundries as well.

Best gravels are low in iron, alkali, and other impurities making them ideal for the manufacturing of refractories.

The wide size range of Best Sand makes it perfect for ladle lining backfill.


Washed and Dried
These high-purity sands and gravels are ideal for all types of foundries. Sub-rounded shape helps to cushion the sand during thermal expansion. High-purity allows Best Sand to be used for iron and steel castings.

• Available in sub-round grain shape
• 99.5% SiO2 purity for high refractoriness
• State-of-the-art blending ensures a consistent silica grade
• Wide range of sizes and distribution

Contains Free Silica. Do Not Breathe Dust. Prolonged exposure to dust may cause delayed lung injury (silicosis). Monographs on the Evaluation of the Carcinogenic Risk of Chemicals to Humans (vol 68, 1997) concludes that there is sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica in the forms of quartz and cristobalite (Group I) in certain industrial circumstances, but that carcinogenicity may be dependent on inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution activity or distribution of its polymorphs.
