Abstract
The transformation of the crystal structure by isomorphous K+-Cs+ substitutions in the non-tetrahedral positions leading to the phase transition has been studied in the series of K1 − x Cs x BSi2O6 solid solutions. The samples have been crystallized from the glass at 850°C for 10 h. According to the data on the crystal structures refined by the Rietveld method, the compositions with 0 ≤ x ≤ 0.35 crystallize in space group \(I\bar 43d\), structural type KBSi2O6, and those with 0.37 ≤ x ≤ 1.0, crystallize in \(Ia\bar 3d\), structural type CsBSi2O6. The reversible cubic-cubic phase transition \(I\bar 43d \rightleftarrows Ia\bar 3d\) occurs in the composition range x = 0.35–0.37.
