It is a widely used chemical substance used in construction, steel, chemical industry and other fields. Calcium oxide can generate new compounds after high-temperature calcination. During the production process, calcium oxide is generally calcined at high temperature in a furnace. At high temperature, calcium oxide decomposes to produce oxygen and metallic calcium, while calcium reacts with carbon dioxide in the air to form calcium carbonate.
