• The major use of quicklime is in the basic oxygen steelmaking (BOS) process. Its usage varies from about 30 to 50 kilograms (65–110 lb) per ton of steel. The quicklime neutralizes the acidic oxides, SiO2, Al2O3, and Fe2O3, to produce a basic molten slag. • Ground quicklime is used in the production of aerated concrete blocks, with densities of ca. 0.6–1.0 g/cm (9.8–16.4 g/cu in).

CALCIUM OXIDE PROPERTIES AND CHARACTERISTICS. Calcium oxide is soluble in water and glycerol. It features a molar mass of 56.0774 g/mol, a melting point of 4,662° F (2,572° C) and a boiling point of 5,162° F (2,850° C). Although calcium oxide is a non-flammable material, it does require the implementation of certain safety precautions when handled, stored or used in manufacturing.
