2018-11-30  The thermal decomposition of limestone in traditional lime kilns is characterized by an environment of not very high temperature but longer residence time. When wood is used, a heat is radiated through the kiln and although it does not reach high values, the heat is homogeneous; which makes the lime remain most porous, favoring the calcination complete of the stone [33] .

2009-6-30  Thermal decomposition behaviour of ten Indian limestones of marine origin have been studied by thermogravimetric (TG) and differential thermal analysis (DTA). DTA curves of limestone samples show asymmetric peak with index of shape about 0. 25. The size of calcite characteristic endothermic DTA peak remains unaffected due to the presence of impurities such as SiO2 and Al2O3.

2015-10-19  Thermal decomposition of dolomite in the presence of CO 2 in a calcination environment is investigated by means of in situ X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The in situ XRD results suggest that dolomite decomposes directly at a temperature around 700 °C into MgO and CaO. Immediate carbonation of nascent CaO crystals leads to the formation of calcite as an ...
