Where to find Silicon
Earth's Crust
Silicon is the second most abundant element in the Earth's crust, primarily found in silicate minerals and silicon dioxide (quartz). It is not found as a native element.
Industrial Production Sites
Elemental silicon is produced industrially from quartz (silica) through carbothermic reduction in electric arc furnaces. Major producers include China, Russia, Norway, Brazil, and the United States.
Collecting tips
- Distinguish from Native Elements. Do not expect to find native silicon in nature. Any metallic-looking, dark gray, brittle substance found in a geological setting is highly unlikely to be elemental silicon. It is far more probable to be a sulfide mineral, an oxide, or a man-made artifact.
- Focus on Silicon Compounds. When studying silicon in a geological context, focus on its compounds, such as quartz (SiO2), feldspars, micas, and other silicate minerals, which are ubiquitous rock-forming minerals.
Quick Check
- Color:
- Dark gray to bluish-gray (for elemental silicon)
- Luster:
- Metallic to submetallic (for elemental silicon)
- Streak:
- Grayish-black (for elemental silicon)
