The Raman spectrum of polycrystalline vaterite is presented and compared to spectra of calcite and aragonite, the other two common CaCO3 polymorphs; Raman spectroscopy easily distinguishes between these three polymorphs. An important feature of the Raman spectrum of vaterite is splitting of both the 1...

Calcium carbonate includes natural fine-ground calcium carbonate (FGCC) produced from limestone, marble, and chalk deposits, and precipitated calcium carbonate (PCC), also referred to as synthetic or light calcium carbonate. This report covers the markets that consume fine grades of calcium carbonate...

Micro-Raman spectroscopy of early-stage calcium carbonate discs show only a single broad peak at∼1,085 cm−1(indicative of amorphous calcium carbonate) for both core (C) and edge (E) regions of a single immature initial disc without platelets, as observed by SEM. At the intermediate ...
Influence of polyvinylpyrrolidone on the precipitation of calcium carbonate and on the transformation of vaterite to calcite. J. Cryst. Growth 250, 516–524. https://doi.org/10.1016/s0022-0248(02)02484-3 (2003). 48. Buzgar, N. & Apopei, A. I. The Raman ...
Calciumcyanamide can be used as afertilizer because it reacts with waterto give ammonia and calcium carbonate:CaCN2(s) + 3H2O(l)→ CaCO3(s) +2NH3(g)It is also used in the production ofmelamine, urea, and certain cyanidesalts. View all Production Methods Calcium cyanamide was first ...
Also, otoliths are composed of calcium carbonate and protein [50]. Download: Download full-size image Fig. 11. (A) Optical photograph of sample No. 3; (B) IR spectrum of the peaks characteristic of calcite in a protein matrix, from the area corresponding to the white circle on the map...
(see Methods: preparation of Ca2+/ds-DNA complex) increases the relative intensity for peak 2 (−5 p.p.m.), indicating a similar interaction of the Ca2+ions with the ds-DNA. A very similar spectrum was obtained for the 2 h sample, in line with the interaction of ds-DNA with...
