2026-07-02 Controllable synthesis of submicron spherical calcite calcium carbonate and data related to the regulation of reaction parameters doi:10.57760/sciencedb.31896 en This dataset corresponds to the research on the synthesis of submicron spherical aragonite calcium carbonate from ammonia stripping calcium solution (industrial solid waste) using an optimized solution mixing method. It systematically collects the characterization data of calcium carbonate's crystal form, morphology, and particle size under different reaction parameters (reactant molar ratio, stirring rate, reaction time, temperature, aging time, types/proportions of impurity ions). It also includes the complete set of characterization data such as XRD, FT-IR, Raman, TG-DSC, SEM, and laser particle size analysis of the spherical aragonite product under the optimal synthesis conditions. Additionally, it contains the dynamic monitoring data of pH, conductivity, and Ca²⁺ concentration during the reaction process. The dataset provides original experimental data support for the crystal type regulation, particle size control, and high-value utilization of aragonite calcium carbonate, as well as offers references for the large-scale preparation and application research of this material.
