![]() Another important siliceous material that has been used as a building material for a long time is loam, which was initially used in branch-fiber clay construction, later in brick form. A typical example of an early stone structure is Stonehenge. Silicon compounds, especially rocks, have traditionally played an important role in human history as a building material. The occasionally encountered translation of silicone is a false friend, because silicones are a class of chemical compounds of silicon. It is included, for example, in the name Silicon Valley. Both spellings originate from the Latin term silicia, silica ', associated with Latin silex' pebble ',' rock '.

Elemental silicon is non-toxic to the human body, silicon in bound silicate form is important for humans. Silicon is extremely important for the electronics and since 2018 in isotope-pure form also serves for the definition of the kilogram. Pure, elemental silicon has a gray-black color and has a typically metallic, often bronze to bluish luster. Silicon is a classic semi-metal, therefore has both properties of metals and non-metals and is an elemental semiconductor. In terms of mass fraction (ppmw), it is the second most abundant element in the earth's shell after oxygen. ![]() ![]() Period of the Periodic Table of the Elements.
