Calcium oxide commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. ... Both it and a chemical derivative (calcium hydroxide, of which quicklime is the base anhydride) are important commodity chemicals.
Its main uses are to neutralise acidic oxides in steel making, the production of aerated concrete blocks, the production of glass, calcium aluminate cement, and organic chemicals.
The challenges of pumping calcium oxide come from its aggressive nature and the fact that its viscosity changes with temperature.
