Ispitan je mehanizam visoko temperaturskih faznih transformacija
cezijum (Cs) izmenjenih zeolita tipa LTA i klinoptilolita (CLI). Analizirane su
osobine dobijenih faza u pogledu termalne stabilnosti i otpornosti na luţenje
jona cezijuma. Rezultati pokazuju da su dobijene stabilne kristalne
alumosilikatne strukture polucita (CsAlSi2O6) i faze CAS (CsAlSi5O12) koje
mogu biti matrice za imobilizaciju Cs jona...
The mechanism of high-temperature phase transformation of cesium (Cs)
exchanged zeolites such as LTA and clinoptilolite (CLI) was investigated.
Thermal stability of obtained phases and their resistance to Cs ion leaching was
also analysed. It was shown that the obtained stable, crystalline alumosilicate
structures of pollucite (CsAlSi2O6) and CAS phase (CsAlSi5O12) can be used as
matrices for Cs ion immobilisation...
