Calcium oxide and calcium hydroxide are inexpensive bases used extensively in chemical processing, although most of the useful products prepared from them do not contain calcium. Calcium oxide, CaO, is made by heating calcium carbonate, CaCO 3, which is widely and inexpensively available as limestone or oyster shells:
Uses of Calcium Oxide. The low cost and desirable chemical properties of calcium oxide (burned lime) are reflected by its consumption on a very large scale by both the cement and the iron and steel industry. In both cases in situ lime preparation from limestone by heat is an integral part of the process.

(a) Calcium oxide, CaO. This is the only compound to which the term lime may be correctly applied. Calcium oxide is variously known as unslated lime, burnt lime and quicklime. It is manufactured by roasting calcitic limestone in a furnace. Calcium oxide is caustic and hygroscopic and is sold commercially in powder and granular forms.
Jul 07, 2016 · In steelmaking process, quicklime is used to produce CaObased slag. Although rapid dissolution of quicklime is required for highefficiency refining, it is known that the rate decreases when dicalcium silie (C 2 S) layer forms around the quicklime by reacting with slag. The equation that driving force is the difference of CaO content between in slag and a liquid phase of slag saturated by ...
