Quicklime Stone

Quick Lime is a Calcium oxide formed by calcining calcium carbonate (lime stone) so that carbon di-oxide is liberated. Quick Lime is also called as burnt lime, handpicked lime, calcining lime, lump lime or caustic lime. A caustic substance that is prepared by burning calcium carbonate lime stone at approximately 900 degree Celsius, at this high temperatures carbon dioxide is driven off and the lime Stone is converted to quick lime. A chemical compound with formula (CaO) it is a whitish, odorless alkaline substance, that does not dissolve well in water. It can be used as a lining material. Major use is in various industrial processes like metal smelting, paper bleaching, sulphur neutralization in sugar and so many. It is used in many water and waste water treatment operations such as softening. Quicklime is created by heating limestone as shown in the following equation: 

Chemical formula : CaCO3 + HEAT = CaO + CO2
