Industrial Raw Silica Flour industrial minerals is a very finely divided, highly purified form of crystalline silica that consists of particles of up to 150 μm in diameter. Crystalline silica is milled to a fine powder by crushing, grinding, or ball milling to produce the flour. Silica flour is used as an abrasive additive in soaps, skin care products, toothpastes, and paints, and as a filler in construction chemicals and pharmaceuticals. It also is used in foundry work and in glass, ceramic, porcelain, tile, and clay production.

Silica Flour is used as Industrial Raw Materials with other industrial raw material products such as Calcium Carbonate, Limestone, Aggregate, Quicklime, Talc, Volcanic Rock and Abrasives. Products containing silica have been used for thousands of years to build and make things – and it is a key ingredient in many products we use every day. Silica flour is used to form a stronger and less permeable cement, especially for high-temperature applications. The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size. Because sand has a negligible degree of porosity it has an extremely low specific surface area. Ground silica sand is produced in a similar manner, except that pulverizing is included. Ground silica can easily be distinguished under the microscope because it has irregular grains.
