Difference Between Quicklime and Hydrated Lime | Compare ...

Aug 16, 2018· The major source for both quicklime and hydrated lime is the limestone. Therefore, like limestone, these compounds are also alkaline. We call quicklime as "burnt lime" because we produce it by the thermal decomposition of limestone. We call hydrated lime as "slaked lime" because we produce it by quenching quicklime with water.

The first decomposition of limestone created a surface area of 17 m 2 /g attributed to pores in the range of 10–100 nm (Fig. 1b). The lime's surface area is close to that predicted by Mai and Egdar (Mai and Edgar, 1989) after calcination and sintering, and similar pore volume distributions were reported by Rodriguez-Navarro et al. (2009).

process of converting limestone into lime - MC World

Limestone when heated starts decomposing into lime (CaO) and carbon di-oxide (CO2) at 810 deg C. The process is called calcination of limestone. It is a thermal treatment process which is carried out for the thermal decomposition of the raw limestone for the removal of LOI (loss on ignition) or carbon di-oxide (CO2) part of its composition.

Calcination - Wikipedia

In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g). The standard Gibbs free energy of reaction is approximated as ΔG° r ≈ 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.

Thermal decomposition of natural dolomite

Abstract. Thermal decomposition behaviour of dolomite sample has been studied by thermogravimetric (TG) measurements. Differential thermal analysis (DTA) curve of dolomite shows two peaks at 777⋅8°C and 834°C. The two endothermic peaks observed in dolomite are essentially due to decarbonation of dolomite and calcite, respectively.

This activity illustrates some of the chemistry of limestone (calcium carbonate) and other materials made from it. Calcium carbonate is heated strongly until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater).
