From aqueous NaOH/Ca(OH)2/NaAl(OH)4 mixtures, after allowing short reaction times we observed the precipitation of Ca(OH)2(s) at lower, and a mixture of Ca(OH)2(s) and a layered double hydroxide, hydrocalumite (HC) at higher aluminate concentrations. From the maximum aluminate concentration, the solubility product of hydrocalumite-hydroxide, described by the formula [Ca2Al(OH)6]OH·nH2O, was determined within the temperature range of 25-75 °C. Additionally, an upper limit for the formation constant of the ion-pair CaAl(OH)4+ was computed, improving our understanding of the equilibrium behavior of these mixed systems at varying concentrations. This research contributes to the knowledge of the solubility characteristics of layered double hydroxides, thus providing essential insights for applications in materials science and chemistry.
