Cesium Bearing Ultramarine Prepared From Zeolites

Add time:08/27/2019    Source:sciencedirect.com

Pigments analogous to ultramarine with various colors including pink have been prepared mainly from zeolites A and also from X by a thermal treatment with sulfur and various amounts of Cs2CO3. The bulky Cs+ cations introduced into zeolites reduce markedly a size of their pore openings and that of inner voids and subsequently affect the type and distribution of generated sulfur chromophores. It is likely that the chromophores in cesium-rich samples occupy rather the shrunken voids of α-cavities but not the sodalite units.
