K a o l i n is it an auto silicate on a popular silicate or sheet silicate or cyclic silicate
Answers
Explanation:
Silicates are the minerals containing silicon and oxygen in tetrahedral SiO44- units which are linked together in several patterns. Depending on the way the tetrahedral units are linked, the silicates are classified into the following types.
Ortho silicates (or Neso silicates) are the simplest silicates which contain discrete SiO44- tetrahedral units.
structural representation of orthosilicates
E.g. 1) Phenacite - Be2SiO4
2) Willemite - Zn2SiO4
Note: The Be and Zn ions are tetrahedrally surrounded by the oxygen atoms of silicate.
3) Olivine - (Fe/Mg)2SiO4 : The cations are octahedrally coordinated to the oxygen atoms of the silicate.
4) Zircone - ZrSiO4 : The coordination number of Zr4+ is 8.
