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} + Heat = {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:
