The Specific Gravity Of Metallic Silicon

The specific gravity of industrial silicon is 2.33 (at 18°C).

Industrial silicon, also known as metallic silicon, is a product that appeared in the mid-1960s. Metallic silicon is a product smelted from silica and carbonaceous reducing agents in a submerged arc furnace. The content of the main component silicon element is about 98% (in recent years, silicon with a content of 99.99% is also listed in metallic silicon), and the remaining impurities are iron, aluminum, calcium, etc.

Specific gravity is also called relative density. The specific gravity of solids and liquids is the ratio of the density of the substance (completely dense state) to the density of pure H2O at standard atmospheric pressure and 3.98°C (999.972 kg/m3). Specific gravity is a dimensionless quantity, that is, specific gravity is a unitless value, which generally changes with temperature and pressure. Specific gravity is abbreviated as s.g.. The density of industrial silicon is 2.32-2.34 g/cm3, so its specific gravity is 2.33.

Additional Notes:

Melting Point: ~1,414°C

Density: ~2.33 g/cm³

Common Uses: Semiconductor industry, solar cells, alloys, and silicones.
