“…Reusing magnesium chloride solution for frequent carbonation cycles, on the other hand, may not necessitate recrystallization and purification [6], [7]. However, precipitated Mg(OH)2 could form in the Ca-rich solution during carbonation, limiting it to the direct carbonation system [8], [9]. As a result, it was proposed in the current study that MgCl2 has the potential for carbonate mineral forming solution-derived green mussel shell powders [10].…”

Green mussel shells are one of the calcium carbonate-rich biogenic sources. They contain 95.7 to 98.2 wt. % calcium. The high calcium content of green mussel shells was extracted and converted into calcium oxide material in the study by calcination at 900°C for 5 h. Later, at stirring times of 30, 60, 90, and 120 minutes, a solution medium containing magnesium chloride was used to dissolve the resulting calcination powder and subsequent carbonation for producing PCC (precipitated calcium carbonate). According to XRD, Rietveld, and FTIR analyses, the resulting PCC product with calcite-containing Mg was obtained primarily for a short stirring time of 30 minutes during the carbonation process, whereas calcite and aragonite were generated at longer stirring times (from 60 to 90 minutes). Instead, brucite was obtained after 120 minutes of stirring. The PCC product has a non-uniform polyhedrallic morphology of various small and large sizes as observed by SEM. This powder processing method allowed for faster PCC synthesis at a lower cost while requiring no chemical addition to increase basicity.

“…Calcination could also be used to valorize unused and alkaline biogenic waste [3][4][5]. Significant effort has been invested in researching the potential biogenic wastes produced by the carbonation process, with a focus on developing processing routes that increase chemical reactivity with CO 2 while reducing energy requirements [6]- [8].…”

“…As a polymorph with the most thermodynamic stability, calcite is the most critical crystal type for industrial applications. Currently, decomposition precipitation, − carbonation, − microemulsion, − and vapor-phase diffusion , are methods of preparing calcium carbonate (CaCO 3 ). Carbonization is an eco-friendly method used in industrial production because of the simple operation process and a small investment in equipment, which however involves a solid–liquid–gas state in a solution.…”

As an essential inorganic material, calcium carbonate (CaCO 3 ) is one of the most abundant minerals in nature, whose preparation by the carbonation of calcium hydroxide [Ca(OH) 2 ] suspension involves complex physical and chemical processes due to the presence of gas−solid−liquid phases. It is challenging to accurately predict the final morphology of CaCO 3 . In this paper, a novel spindleshaped CaCO 3 covered with a mass of nanoscale rhombic calcite subunits was prepared via the carbonation method. This structure was mainly formed by the aggregation of nanoparticles in the pre-reaction stage and turned into a classical ion− ion growth process at the stage of the late reaction. During the pre-reaction period, solid Ca(OH) 2 kept the solution supersaturated and made the aggregation of nanoparticles dominate and assemble to form the nanochains of CaCO 3 . Subsequently, the aggregation of nanochains formed a dumbbell shape, which was accompanied by the recrystallization of nanoparticles inside aggregates to create an ordered single-crystal spindle structure. Finally, the concentration of Ca(OH) 2 decreased, and a layer of nanoscale rhombic calcite subunits grew on the surface of spindle CaCO 3 . This work will provide new insights into the industrial preparation of CaCO 3 with controlled morphology and contribute to understanding the biomineralization of aggregation-based growth in aqueous solutions.

“…The control of the growth of CaCO 3 precipitates obtained in chemical methods is an active area of study due to the numerous applications of small CaCO 3 particles and inhibition of scales in industrial equipment. [26][27][28][29] One effective approach to limiting CaCO 3 overgrowth is the adsorption of additive or impurity ions on fresh precipitates. Studies show that foreign ions, 29 surfactants such as sodium dodecyl sulfate, 30 oxyanions, 31 and organic chemicals or polymers 26,32 can be used to control the growth rate and sizes of CaCO 3 particles.…”
