- Abstract
- Ultramarine blue pigments ( in the form of highly concentrated KBr
discs) have been examined by transmission infrared spectroscopy.
Evidence of entrapment of carbon dioxide in the natural pigment from
Afghanistan was indicated by the absorption band at 2340 cm(-1) and a
low frequency satellite corresponding to the (CO2)-C-13 isotopologue.
The thermal behavior of natural ultramarine, has been studied by FTIR,
UV-vis spectroscopy, and XRD, from 300 K to 1120 K. Measurements show
that CO2 and the encapsulated S-3 chromophore behave in the same way
during the heating experiment, starting to be released only at about
670 K when the apertures of the sodalite beta-cages became larger as an
effect of temperature. (C) 2008 Elsevier B. V. All rights reserved. (literal)
