متن کاملSpinning up the polymorphs of calcium carbonate
Controlling the growth of the polymorphs of calcium carbonate is important in understanding the changing environmental conditions in the oceans. Aragonite is the main polymorph in the inner shells of marine organisms, and can be readily converted to calcite, which is the most stable polymorph of calcium carbonate. Both of these polymorphs are significantly more stable than vaterite, which is th...
متن کاملPrecipitated Calcium Carbonate Prepared by Batch and Semicontinuous Processes
A comparison of the physical-chemical properties of precipitated calcium carbonate (PCC), prepared by batch and semicontinuous processes, is presented. In both processes, PCC, was synthesized by carbonation of slaked lime. In the batch process the experiments were performed by varying the initial mass concentration and temperature, and the semicontinuous process was conducted by varying the ini...
متن کاملPrecipitated Calcium Carbonate Nano-Microparticles: Applications in Drug Delivery
Calcium carbonate (CaCO3) is an abundant mineral that has several uses in paper [1], Portland cement [2] and steel making [3], as agricultural input for soil modification [4], and food additive in soy milk and dairy products. Due to its high biocompatibility, CaCO3 is also employed in many pharmaceutical (anti-acid, dietary supplement for child and postmenopausal women), biological (scaffolds f...
متن کاملInfluence of relative humidity on the carbonation of calcium hydroxide nanoparticles and the formation of calcium carbonate polymorphs
A consolidating product based on nanoparticles of slaked lime (Ca(OH)2) dispersed in isopropyl alcohol was exposed under different relative humidities (RH), 33%, 54%, 75% and 90% during 7, 14, 21 and 28 days. The characterization of the calcium hydroxide nanoparticles and the formed calcium carbonate polymorphs has been performed by Micro-Raman spectroscopy, Transmission Electron Microscopy (TE...
