Abstract

Vacant Sr‐feldspar was synthesized by thermal transformation of FAU zeolite and the structure was refined (space group I2/c). Two refinement procedures were performed: with and without micro strain modelling. Reliable structure model was achieved only with including micro strain modelling. Vacancies in the Sr^2+^ positions produce micro strain. The concentration of vacancies was the highest along [011] direction. (© 2007 WILEY ‐VCH Verlag GmbH & Co. KGaA, Weinheim)
