Abstract
The missing link in the series of ultramarine pigments, a synthetic sodalite containing yellow S2 - ions, was prepared by thermal decomposition of a thiocyanate sodalite under vacuum or nitrogen. The nature of the product has been elucidated through X-ray powder analysis, VIS/UV-and ESR-spectrometric measurements, and by the observation of the brilliant red fluorescence of the sulfur radical ion S2 -.Keywords
