Collection: Calcium oxide

Quicklime, also known as calcium oxide or CaO (calcined), is a chemical compound that is used in various applications and sectors. Granulated quicklime is the same substance, but in a granular form, which makes it easier to handle and apply. Here are some of its main uses:

  1. Construction industry: Quicklime is used in the production of mortar and concrete, by reacting with water to form calcium hydroxide, which is a fundamental component of these materials.
  2. Steel industry: In steel production, quicklime is used to remove impurities in the steelmaking process, such as silica, phosphorus, and sulfur. Quicklime helps form slag that traps and removes these impurities, improving the quality of the steel.
  3. Water treatment: Quicklime is used in the treatment of wastewater and drinking water to remove impurities, improve alkalinity, soften water and reduce the concentration of heavy metals and other contaminants.
  4. Chemical industry: Quicklime is used as a reagent in the production of chemical products, such as propylene oxide and calcium chloride, among others.
  5. Agricultural industry: Quicklime is used to correct soil acidity and improve nutrient availability for plants. By applying quicklime to the soil, the pH is increased, which improves the soil structure and favors plant growth.
  6. Paper industry: In papermaking, quicklime is used in the process of recovering chemicals from black liquor, which is a by-product of the pulp manufacturing process.
  7. Food industry: Quicklime is used in the production of sugar from sugar cane and sugar beets, as it helps in the clarification of the juice and in the removal of impurities.
  8. Disinfection and Odor Control: Quicklime is used in the disinfection of barns, poultry farms and other enclosures where animals are raised, as it is an effective antimicrobial agent. It is also used to control unpleasant odors in public areas or industrial facilities.
