Description. Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2 ). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.

Silica dust is made up of small particles that can become airborne during work activities with materials that contain silica. Particles that are small enough to be inhaled deep into the lungs are called respirable. The most common form of crystalline silica is quartz. However, it can also occur in the form of cristobalite and tridymite.

Silica vs Quartz: Similarities, Differences, and Proper Use
Jewelry: In jewelry, quartz is often used as a gemstone, while silica is used to make glass. Quartz is preferred for gemstones because it has a higher clarity and hardness, making it more valuable. Silica is preferred for glass because it has a lower melting point and can be easily molded into different shapes.
