Quicklime

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 degrees 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:

  • Standard Quicklime is produced and sold in several sizes ranging from ¼” to 2″.
  • Pulverized Quicklime is available in both a treated and untreated form for use in glass, fiberglass and steel industries.
  • VitaCal® O Calcium Oxide is a very high purity calcium oxide used in both the chemical and food industries.
  • MicroCal® O Calcium Oxide can be applied to a wide variety of chemical manufacturing applications where purity and reactivity are important.
  • PetroCal® O Calcium Oxide is designed to meet the exacting requirements of the petroleum additives industry.
  • PolyCal® O Calcium Oxide is produced for the Rubber and Plastics Industries where tight sizing and reactivity control are essential.
  • ThermoCal® O Calcium Oxide is a product having unique heat generation characteristics.

Standard Quicklime
