Pollucite- and leucite-related phases: A2BX5O12 and ACX2O6

  • 1. Aberdeen Univ. (UK)

Description

Synthesis and crystallographic data on 29 new phases in this family are given. A survey of the crystal chemistry of the complete family, containing 59 phases to date, is presented. The family contains at least seven structural variations, two of which are the pollucite, CsAlSi2O6 and leucite, KAlSi2O6 structures. Correlations between cation size and structure type are presented. Unusual variations in unit cell dimensions as a function of cation size are discussed and the possible relevance of the 'partially collapsed framework' concept of Taylor and Henderson indicated.
