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....
Silica sand and glass industry
· a) Silica sand The discolouring impurities iron and chromium occur within the nonquartz mineral fraction of the sands. Iron can occur as haematite, giving the sand a red colour, or as oxyhydroxidcs (giving a yellow or brown colour) as well as in silie minerals. Chromium occurs as the heavy mineral chromite (FeCr2O4), which is stable during glass manufacture, and so rather than ....
