Sibelco

At Sibelco, we produce the crystalline forms of silica – quartz and cristobalite – as both sands and flours. Silica is hard, chemically inert and has a high melting point, making it a valuable material in a range of appliions and industries, including paints plastics, ceramics, glass, filtration and agriculture.

Silica, Crystalline

Crystalline silica is also used to make products such as glass, pottery, ceramics, bricks, concrete and artificial stone. Industrial sand used in certain operations, such as foundry work and hydraulic fracturing (fracking), is also a source of crystalline silica exposure. Amorphous silica, such as silica gel, is not crystalline silica.

Properties of fused silica

Synthetic silica produced by flame hydrolysis of silicon tetrachloride can have high (> 1000 ppm) or very low hydroxyl content depending on whether a hot chlorination step is employed to remove it. The hydroxyl level can be so high because the silica particles that result from the hydrolysis reaction are extremely fine and therefore have tremendous surface area capable of absorbing moisture ...

Method for Determining Crystalline Silica in Bulk Samples ...

 · A river sand, comprised predominately of coarse silica, will present less of a respirable dust hazard risk than silica , primarily a very fine powder, which would pose a vastly enhanced risk. Although the three abovementioned products may give a similarly high percentage of crystalline silica in the bulk sample, they pose different crystalline silica inhalation hazard risks.
