The kinetics of the thermal decomposition of a limestone and, simultaneously, of the lime growth have been investigated during isothermal treatments by means of in situ High Temperature X‐Ray Powder Diffraction. In particular, four grain sizes of a quarry limestone with differences in terms of mineralogical composition (dolomite content), chemical composition (Fe and Mg amounts), and texture, have been studied. The lime produced during the isothermal treatments was then examined by using Scanning Electron Microscopy. In all samples, limestone decomposition starts with dolomite dissociation, followed by calcite decomposition. Rather than particle size, limestone texture, and dolomite content seem to be the most important factors controlling the starting temperature of calcination and its kinetic behavior.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
