Abstract:The
dissolution of corundum, Al2O3, in water
is considered as a set of reactions of hydration of the solid phase
with the formation of various charge-neutral aqueous Al species. Methods
of quantum chemistry (QC) were used to compute the thermodynamic properties
of several Al forms in the ideal gas state. The combination of QC
results with estimated values of fugacity coefficients of these species
in water permits the evaluation of the concentrations of various Al
forms over corundum and thus the calculation of… Show more
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.
