Abstract - Summary
(short description): | |
The leucite-like compounds with substituted B, KBSi2O6 and CsBSi2O6, are crystallized in different space groups: I-43d č Ia-3d. In this paper we have investigated the transformation of the crystal structure in the KBSi2O6 - CsBSi2O6 series due to the isomorphous substitution of the larger cation Cs+ for the smaller cation K+. The deformation of structure of CsxK1-xBSi2O6 solid solutions x=0.0; 0.2; 0.3; 0.35; 0.375; 0.4; 0.5; 0.7; 0.8; 1.0 under cationic substitution was studied by Rietveld method. The phase transition I-43d ↔ Ia3d occurs within the composition range x=0.375-0.4. The similarity between the chemical and thermal deformation was revealed.
