Facts about silicon element

  • Nice
  • Silicon was discovered by Swedish chemist Jöns Jakob Berzelius, who reacted potassium fluorosilicate with potassium to produce amorphous silicon
  • Silicon gets its name from the Latin “silex,” meaning flint or hard stone. Originally named “silicium
  • Pure silicon has the same crystal structure as diamond, which is made of carbon – the element that sits above silicon in the periodic table
  • Silicon is a metalloid, which means it has properties of both metals and nonmetals.
  • Silicon has a high thermal conductivity and conducts heat well. Unlike metals, it's brittle, and not malleable or ductile
  • Silicon is the second most abundant element in the earth’s crust.Silica in the form of silicon dioxide(SiO2) is the most abundant compound in the earth’s crust
  • Most silicon is used to produce the alloy ferrosilicon. It's used to produce steel. The element is purified to make semiconductors and other electronics
  • Sand has a high percentage of silicon and is the starting material to make high-purity silicon wafers on which semiconductor devices are made
  • Natural silicon consists of three stable isotopes: silicon-28, silicon-29, and silicon-30
  • Silicon is available at extremely high purity. Molten salt electrolysis of silica or other silicon compounds can be used to obtain highly pure element
