New article - silicon dioxide
'''Silica''', or Silcion dioxide SiO<sub>2</sub> is a common chemical component on the surface of the earth. It is a principle component in [[glass]], and [[cement]]. It absorbs water, making it useful in food perservation and when pure, can be used in electronics as an [[electrical insulator]], as it prevents the flow of electric current. When [[covalent bonds]] form a lattice, [[Quartz]] is formed.
<br> Silica forms naturally when oxygen comes into contact with oxygen and is a primary component in sand.
