Description
  • Crystalline CsAlSiO4 was synthesized from a stoichiometric mixture of Al2O3 + SiO2 + Cs2O (plus excess water). The crystal structure of the CsAlSiO4 feldspathoid is built on an ABW framework type, showing a fully ordered Si/Al-distribution in the tetrahedral framework. The only extra-framework site is occupied by Cs, lying off-center in the 8mR-channels. CsAlSiO4 is more likely to retain Cs when immersed in a fluid phase, relative to several other Cs-bearing zeolites. The topological configuration of the Cs-polyhedron (and its bonding environment), the small dimension of the pores and the high flexibility of the ABW framework type would imply a better thermal and elastic stability of CsAlSiO4 than those of the zeolitic Cs-aluminosilicates. In this light, CsAlSiO4 can be considered as a functional material potentially usable for fixation and deposition of radioactive isotopes of Cs..
