The abundance of silicon, causing early interest a chemist. Silicon (SI) in the Earth's crust after oxygen levels, mass fraction 26.3%. Silicon (SI) element is not the first element to be discovered, that is because from Silicon (SI) to restore the Silicon oxide is a very difficult thing.

SI 25.7% per cent of the total weight of the Earth's crust, after oxygen. In nature, usually in the form of oxygen-containing compounds of silicon, one of the most simple of silicon and oxygen compounds of silica, SiO2. Quartz, Crystal is a variant of pure silica. Ores and rocks of the Silicon-oxygen compounds called silicates, more important KAlSi3O8 feldspar, kaolin Al2Si2O5 (OH) 4, layered double hydroxides Mg3 (Si4O10) (OH) 2, MICA KAl2 (AlSi3O10) (OH) 2, H4Mg3Si2O9 asbestos, sodium zeolite Na2 (Al2Si3O10) • 2H2O, Garnet Ca3Al2 (SiO4) 3, Zircon ZrSiO4 quartz and Beryl Be3Al2Si6O18, and so on. Soil, clay and sand are the natural product of weathering of silicate rocks.
