F. Kooli et al., Conversion of protonated magadiite to a crystalline microporous silica phase via a new layered silicate, CHEMPHYSCHE, 2(8-9), 2001, pp. 549
Organic structure-directing agents are necessary to the formation of define
d zeolitic structures; doing without the organic component can simplfy the
reaction immensely. Such a transformation, of protonated magadiite to a new
layered silicate, is reported herein. The picture shows the XRD patterns o
f as-prepared protonated magadiite and the product after simple hydrotherma
l treatment at two different temparatures. After calcination (500 degreesC)
the final material has a surface area of 457 m(2) g(-1).
