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
Silica is one of the most common minerals on earth and is a basic component of soil, sand, and rocks including granite and quartzite. Silica exists in both crystalline and amorphous (non-crystalline) forms. Conversion from amorphous to crystalline form can occur at high heat.
Quartz is one of the crystalline forms of silica, the essential building material for all silicates, and quartz can only form where silica is present in excess of what is consumed in the formation of other silicate minerals. Quartz may also be consumed during the formation of new silicate minerals, in particular at higher temperatures and ...
