Abstract

Polycrystalline analcime film was prepared from hydrogels under hydrothermal conditions. The analcime film of about 200 µm thickness built up on a porous alumina support at temperatures above 160 °C, and the size and crystallinity of analcime increased with temperature. The thickness of analcime film increased with incubation time, and the growth rate at 180°C was faster than that at 160 °C. The analcime film obtained was thermally stable at temperatures up to 700 °C, and no structural changes were observed after treatment in nitric acid solutions below 0.01 m. Analcime had an ion-sieve ability to large sized Cs+ ion, and Ag+ and Rb+ ions of small sizes were incorporated in analcime.
