2014年9月16日 · A better understanding of the whole system obtained from a review of the literature allowed new conclusions to be established. Thanks to that revision and the …

2020年1月29日 · Raman spectroscopy was used because of its structural sensitivity and in situ measurement capability to obtain further insight by studying phase transitions in both ex situ …

1999年2月25日 · In this work, dehydration of CaSO 4 ·2H 2 O and CaSO 4 ·0.5H 2 O in stagnant air was studied by thermo-Raman spectroscopy from 25 to 300°C. The composition could be …

Raman Spectroscopy, a nondestructive method, proved advantageous over X-Ray Diffraction (XRD) in distinguishing different gypsum phases, given its precision over varying light …

1973年1月1日 · The Raman spectrum of anhydrite is analysed and its relation to the spectrum of gypsum discussed. Comparison is also made with some spectra recorded from samples of …

2014年9月29日 · The Raman spectra of each phase of the CaSO4/H2O system were successfully identified for the first time and the contradictions found in literature were critically summarized. …

2014年9月16日 · Compared to XRD, distinguishing γ-CaSO 4 from bassanite using Raman spectroscopy is very straightforward. As demonstrated by Prieto-Taboada et al. (2014) and …

2020年1月29日 · Raman band width determination was demonstrated to enable the quantitative discrimination of -bassanite and -bassanite as well as the postulated three sub-forms of …

High‐quality Raman spectra were used for the characterization of alumina phases of gibbsite, bayerite, diaspore and boehmite. The Raman spectrum of gibbsite shows four strong, sharp …

2014年10月21日 · Although it is known that the CaSO4/H2O system is formed by at least five different phases, this fact is not correctly documented in Raman spectroscopy studies. The …
