What is Precipitated Silica

Precipitated silica, a form of synthetic amorphous silicon dioxide, is derived from quartz sand, a crystalline form of silicon dioxide. The physical properties of precipitated silica can be manipulated during the manufacturing process to deliver products with a wide range of performance-enhancing features engineered for many different end-use applications.

What Is Silica Sand Used For?

Silica has a high melting point, making it an ideal product for use in foundries. An item pressed into the sand leaves an imprint, which the foundry fills with molten metal. Once the cast has hardened, workers lift it from the sand mold and brush away any remaining sand. The relatively small granule size of silica sand is also ideal for filtration.
