Description

Powder sample of GTS-type sodium titanosilicate (Na-GTS) was prepared using a hydrothermal method. The Er3+-exchanged forms [Na4(1-x)Er4x/3Ti4O4(SiO4)3·nH2O] of Na-GTS with the compositions up to x = 0.96 were obtained by shaking the single-phase sample of Na-GTS in the ErCl3 aqueous solutions (25 mL, 0.01-0.5 M) at 25 and 60 °C for 6 h. The Er3+-exchange experiments revealed that the Er3+-exchange amounts (x) increase with increasing the concentration of ErCl3 aqueous solutions and the higher treatment temperature more effectively promotes ion-exchange. Thermogravimetry-differential thermal analysis (TG-DTA) measurements showed that the exchange of Na+ for Er3+ decreases the dehydration temperature and the H2O content. The simulation of powder X-ray diffraction (XRD) patterns suggests that Er3+ ions occupy both 4e and 6g sites in the assumed pseudocubic structure. (author)
