abstract = "A promising method for removal of Cs ions from water and their incorporation into stable crystal structure ready for safe and permanent disposal was described. Cs-exchanged X zeolite was hot-pressed at temperature ranging from 800 to 950 degrees C to fabricate dense pollucite ceramics. It was found that the application of external pressure reduced the pollucite formation temperature. The effect of sintering temperature on density, phase composition and mechanical properties was investigated. The highest density of 92.5 %TD and the highest compressive strength of 79 MPa were measured in pollucite hotpressed at 950 degrees C for 3 h. Heterogeneity of samples obtained at 950 degrees C was determined using scanning electron microscopy. The pollucite hot-pressed at 950 degrees C had low linear thermal expansion coefficient of similar to 4.67 x 10(-6) K-1 in the temperature range from 100 to 1000 degrees C.",
