Preparation. Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln.Calcium oxide, CaO, also known as lime or more specifically quicklime, is a white or grayish white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide.Earth Sciences – The Calcium Cycle (1) Limestone : Calcium is a very common element in nature. It occurs most commonly in limestone rock as calcium carbonate…Calcium is a chemical element with symbol Ca and atomic number 20. An alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to …Health & Safety and Technical notes. Read our standard health & safety guidance.
