Deginta kalkė - Kalcio oksidas (CaO)
Burnt lime
Calcium oxide (CaO), commonly known as quicklime or burnt lime, It is a white, caustic, alkaline, crystalline solid at room temperature
Calcium oxide that survives processing without reacting in building products, such as cement, is called free lime
Industries:
Glass and ceramics
production of glass, calcium aluminate cement, and organic chemicals
production of aerated concrete such as blocks with densities of ca.
the major use of quicklime is in the basic oxygen steelmaking (BOS) process
the quicklime neutralizes the acidic oxides, SiO2, Al2O3, and Fe2O3, to produce a basic molten slag
