2014年4月5日 · Cubic and spindle-shaped CaCO 3 particles were successfully prepared using carbonation method without any additional crystal controlling agent. The experimental results showed that carbonation temperature and initial concentration of Ca (OH) 2 slurry are the main factors to influence the morphology of CaCO 3 particles.

2021年12月1日 · In this study, magnetic layered hierarchical calcium carbonate (MLH-CaCO 3) and magnetic cube-shaped calcium carbonate (MCS-CaCO 3) materials were prepared using a simple coprecipitation method for the removal of Pb(Ⅱ). In addition, the formation processes of the different morphologies of calcium carbonate were reasonably explained.

2021年11月1日 · Calcium carbonate (CaCO3) is an abundant inorganic biomaterial in the manner of different structures (calcite, vaterite, and aragonite) [1, 2]. Thermodynamically, the form of CaCO 3 under normal conditions is β-CaCO 3 (calcite).

2023年9月27日 · This also shows that the CaCO 3 prepared by adding acetic acid, salicylic acid, and EDTA has a cube structure with a particle size of about 4~7 μm. Two inorganic acids were also tested as an additive.

2021年10月1日 · In this study, magnetic layered hierarchical calcium carbonate (MLH-CaCO3) and magnetic cube-shaped calcium carbonate (MCS-CaCO3) materials were prepared using a simple coprecipitation method...

2021年10月1日 · The novel method for nanoscale Fe3O4@CaCO3 composites synthesis was proposed and showed the “pitfalls” of DOX-loaded nanocomposites and provided step-by-step guidance on efficient, smart, anticancer nanoconstruction fabrication.

The volume of a cube is given by the formula: V = s^3, where V is the volume and s is the length of one side of the cube. Step 4: Identify the relevant information. We know that CaCO3 is made up of one calcium (Ca) atom, one carbon (C) atom, and three oxygen (O) atoms.

2022年8月22日 · In this review, the controlled synthesis of CaCO 3 is first examined, including Ca 2+ –CO 32− systems, solid–liquid–gas carbonation, water-in-oil reverse emulsions, and biomineralization.

2017年9月26日 · Calcium carbonate from geological sources (geo-CaCO 3, e.g., calcite, aragonite) is used extensively in removing heavy metals from wastewater through replacement reaction. However, geo-CaCO 3 has an intrinsically compact crystalline structure that results in low efficiency in pollutant removal and thus its use may produce enormous sludge.

Calcium carbonate (CaCO3) microspheres of vaterite polymorph were successfully obtained by combining calcium chloride (CaCl2) and sodium carbonate (Na2CO3) in the presence of poly (acrylic acid) (PAA) and sodium dodecyl benzene sulfonate (SDBS).
