Silicium

History
 
Silicon was discovered by Jens Jakob Bertseliusom in 1825. He proceeded to restore the response of the silicon tetrafluoride. A new element was named silicium from the Latin «silex - rock». The industrial way was opened Russian scientist N.N. Beketov in the second half of the 19 th century. The first chips based on silicium began to appear in the 1970's.

Nowadays

Silicon needs to deoxidization in metallurgy and alloying additives. It improves strength and corrosion resistance of steels and alloys on the basis of non-ferrous metals. Silicone rubber is top frost and heat resistant. Of the compounds of silicon and iron manufacture acidproof materials. Silicon is widely used in solar batteries. The main elements for the manufacture of glass is silicon or, more precisely its oxide. There is also a so-called silicate adhesive, called a “glass”. Silicon is a part of some precious and semiprecious stones such as amethyst violet.
