Web2 days ago · The FTIR band position and allocation of the vibrational mode are demonstrated in Table 4. The FTIR peak located in Fig. 4 (a) and (b) in the range of 987 cm-1 and 1403–1406 cm-1 are the characteristics of the C–O bending and stretching mode (carbonate groups). WebSep 6, 2024 · Herein, we successfully monitored the moisture-induced crystallization process of ACC via in situ FTIR spectroscopy, which is very sensitive to the specific changes of the different vibrational modes of carbonates and water molecules. WebMar 9, 2012 · Calcium carbonate decomposes under well-defined conditions giving CaO (solid) and CO2 (gas). The process kinetics are known to be strongly influenced by the CO2 partial pressure and temperature. In dynamic conditions, as in thermogravimetric analysis (TG) and differential thermal analysis (DTA), kinetics influence the observed heat effect … life operation
