Burnt lime or Quicklime is an change call for the chemical compound calcium oxide. You Can Get from Rajasthan Lime. Calcium oxide is represented with the aid of the chemical formulation CaO. It exists as a white crystalline stable at standard situations for temperature and stress. It is inexpensive and abundant.
How to Prepare Quicklime?
Quicklime can be easily organized from the decomposition of limestones or sea shells that are comfortably to be had. Since limestones and sea shells contain calcium carbonate, they can be processed to produce burnt lime via the system of calcination.
During the method of calcination, the byproducts are carbon dioxide and burnt lime.
CaCO3→CaO+CO2
Properties of Quicklime
Physical Properties
It is a shapeless white amorphous powder with high melting and boiling factors, which can be 2,572oC or four,662oF and a pair of,850oC or 5162oF, respectively. It is a highly insoluble and thermally stable compound, therefore it's miles suitable for glass and ceramic programs. It does now not conduct energy. It is insoluble in alcohol and difficult to decompose because it's far very strong.
Chemical Properties
Calcium oxide reacts easily with water to form calcium hydroxide which is used for plenty commercial purposes.
CaO+H2O→Ca(OH)2
Important Questions
1. What are the viable health dangers that calcium oxide can purpose?
Ans: Quick lime can motive inflammation to the eyes and pores and skin; consequently, full personal protecting equipment should be worn earlier than dealing with this compound. If quicklime comes in contact with the eyes, it is suggested to very well wash the eyes and call the doctor right away. If quicklime dust is inhaled, there's a possibility of inflammation inside the breathing tract.
2. Difference between Quicklime and Hydrated lime?
Ans: Hydrated lime is shaped while water is delivered to powdered quicklime and the ensuing combination is positioned in a kiln or an oven and ten pulverised with water. Meanwhile, Calcium Oxide is shaped from the thermal decomposition of calcium carbonate. Calcium oxide is said to be extra reactive than hydrated lime due to its higher density.

3. How do you outline the time period calcination?
Ans: Calcination is the coaching technique of burnt lime wherein reactants are thermally decomposed at high temperatures. But it is ensured that the temperatures are less than their respective melting factors.
Conclusion
It is white amorphous solid, and a tremendously solid compound with a melting factor of round 2600oC. Above 2400 levels celsius, it emits an excessive glow. Its appearance varies from white to pale yellow or brown underneath wellknown situations. It is used for many commercial purposes. It is used for production metallic, iron, paper, pulp, primary oxygen steelmaking technique, and many others.
