At Mississippi Lime, our calcium oxide (CaO), or commonly referred to as quicklime, is a high calcium content derivative of our 98.5% pure calcium carbonate (limestone).  Calcium oxide is produced by heating calcium carbonate to 2000 deg F where carbon dioxide disassociates as a gas from the calcium carbonate:

Calcium Carbonate + Heat = Calcium Oxide + Carbon Dioxide
   {CaCO₃}                            =   {CaO}         +   {CO₂}

Calcium oxide can be utilized in a variety of applications because of its physical and chemical qualities.  Mississippi Lime’s calcium oxide product families and description are shown below:
