Synthesis of silica-sodalite from non-aqueous systems

Abstract

The aluminosilicate sodalite has been known since antiquity1. It occurs naturally as the polysulphide-containing mineral lapis lazuli1 and as a salt-bearing feldspathoid2 and has also been synthesized as the zeolite basic sodalite with the formula Na6(Al6Si6O24) · xNaOH · (8−2x)H2o (ref. 2). The structure is an open framework of relatively large cages which… (More)
