Abstract
Cesium can be encapsulated in crystalline aluminosilicates or borosilicates of ANA framework type byhydrothermal synthesis from alkaline solutions at a temperature as low as 115 °C. No miscibility gap isobserved in the borosilicate–aluminosilicate solid solution. The presence of cesium in the synthesis batchslightly decreases the yield of incorporation of boron in the silicate framework. Nanocrystals from 25 to50 nm are formed in most of the synthesis conditions.
