Calcium oxide (CaO, CAS Reg. No. 1305-78-8) is also known as lime, quick lime, burnt lime, or calx. Lime does not occur naturally since it reacts so readily with water (to form hydrated lime) and carbon dioxide (to form limestone). It is produced from calcium carbonate, limestone, or oyster shells by calcination at temperatures of 1,700-2,450℃.

Product Usage
Calcium oxide, commonly known as quicklime, is a vital industrial chemical with diverse applications rooted in its high reactivity and alkalinity. Its primary use is in the steel industry, where it acts as a flux to remove impurities like phosphorus and sulfur during smelting. In environmental protection, it is essential for flue gas desulfurization and wastewater treatment, effectively neutralizing acidic effluents and precipitating heavy metals. Furthermore, it serves as a critical building material for manufacturing calcium silicate board and mortar. In the chemical sector, it is a key reagent for producing calcium carbide and a high-efficiency desiccant for removing moisture from gases and organic solvents.
