When calcium carbonate is heated in a process referred to as burning or calcining, it forms calcium oxide, also known as quicklime. This reaction is reversible such that cooling the calcium oxide will change it back to calcium carbonate....
Benefits Of Pelletized Lime | Baker Lime
Pelletized lime, in essence, is powdered lime that is mixed with an adhesive to form small pellets. The process of making these pellets is very similar to the process of making powdered lime – slabs of limestone are continuously crushed and ground until the stone forms small particles of powdered lime....

Calcium oxide | chemical compound |
Calcium oxide, CaO, also known as lime or more specifically quicklime, is a white or grayish white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide. At room temperature, CaO will spontaneously absorb carbon dioxide from the atmosphere,....
Calcium carbonate Essential Chemical Industry
In the chemical industry, large quantities of limestone are heated to ca 1500 K to form calcium oxide, known as quicklime: Water can be added to lime to form calcium hydroxide. The process is known as 'slaking'. Solid calcium hydroxide is known as slaked lime or hydrated lime, and solutions and suspensions in water as milk of lime....
Effects of hydrated lime and quicklime on the decay of ...
excess of 800°C, carbon dioxide is evolved, resulting in a white residue of calcium oxide (known variously as quicklime, unslaked lime or burnt lime). By adding water to quicklime calcium hydroxide is formed (known variously as hydrated lime or slaked lime) in an exothermic reaction. On exposure to air, absorption of carbon...
