Encapsulation of Cs/Sr contaminated clinoptilolite in geopolymers produced from metakaolin [PDF]

open access: yes, 2015
The encapsulation of caesium (Cs) and strontium (Sr) contaminated clinoptilolite in Na and K based metakaolin geopolymers is reported. When Cs or Sr loaded clinoptilolite is mixed with a metakaolin geopolymer paste, the high pH of the activating solution

Hydrothermal transformation of clinoptilolite

open access: yesBulletin of Materials Science, 1985
Procedure for hydrothermal transformation of natural clinoptilolite at 160°C is described. The synthesis is carried out in the system Na2O-Al2O3-SiO2-H2O. Products of 24–168 hr runs are characterized by x-ray diffraction,ir spectroscopy, energy dispersive analysis of x-rays (edax), and electron microscopy.
