SiO 2 is an oxide of silicon with a chemical name silicon dioxide. It is also called Silica or Kalii bromidum or Silicic oxide or silicic acid. It is widely found in nature as quartz. It is obtained as a transparent to grey, in its crystalline or amorphous powdered form. It is odourless and tasteless compound.
Silicon dioxide, also known as silica, is a chemical compound, the oxide of silicon. Its chemical symbol is SiO 2. It is known for its hardness since the 16th century. It has an important compound used in most types of glass and other hard substances such as concrete, porcelain and stoneware. It is made up of 2 oxygen atoms and 1 silicon atom.
Quartz is a hard, crystalline mineral composed of silica ( silicon dioxide ). The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.
Silicon dioxide or silica, as it is commonly known as, is an important constituent of sand. However, it is found in several other forms too. In this article, we shall look into the physical and chemical properties of silicon dioxide, and learn a little about its molecular structure. Read on… We all remember visiting sandy beaches in our childhood.
