and are a component of soil, sand, and rocks. Silica minerals are sometimes called "free silica," to distinguish them from other silicates, complex mineral structures containing bound silicon dioxide. Crystalline silica is a collective term that can refer to quartz, cristobalite, tridymite, and several other rare silica .
Silica exists in nine different crystalline forms or polymorphs with the three main forms being quartz, which is by far the most common, tridymite and cristobalite. It also occurs in a number of cryptocrystalline forms. Fibrous forms have the general name chalcedony and include semiprecious stone versions such as agate, onyx and carnelian.
Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are

Mar 11, 2014· This is important information since it draws attention to a silica exposure hazard. I am concerned that the term "engineered stone" does not warn workers about the potential silica exposure. Maybe "engineered silica stone" or "engineered quartz counter top" would be better.. Descriptive terminology in this case appears to be critical.
