Notes on Carbonates


Limestone (calcium carbonate - CaCO3) is used as a building material and in the manufacture of:

  • Iron – in the blast furnace

  • Glass – heated with sand and soda (sodium carbonate)

  • Cement – heated with clay in a kiln

  • Concrete/ mortar – mixed with sand and water (and crushed rock)

  • Lime – thermal decomposition


Lime/ quicklime (calcium oxide - CaO) is made from limestone (calcium carbonate – CaCO3) by thermal decomposition.


Calcium carbonate CaCO3 + heat -----> calcium
