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 Properties: CAS number 1305-78-8 WE number 215-138-9 Chemical formula CaO Molar mass 56,08 g/mol Customs tariff code 28259019 pH 12,3
