Crystalline silica is a bigger worry for the health of our lungs. The most common form of crystalline silica is quartz, which is found in sand, gravel, clay, granite, diatomaceous earth, and many other forms of rock. Non-crystalline silica is found in glass, silicon carbide, and silicone. These materials are much less hazardous to the lungs.

The physical and chemical properties of silica make it suitable for many uses. Most silica in commercial use is obtained from naturally occurring sources, and is categorized by end-use or industry (IARC, 1997; NTP, 2005). The three predominant commercial silica product categories are: sand and gravel, quartz crystals, and diatomites.
