Verified Syntheses of Zeolitic Materials

2nd Revised Edition

Preface to the second edition

The first edition of Verified Syntheses of Zeolitic Materials was published as Volume 22, Nos. 4-6 of Microporous and Mesoporous Materials (30 June 1998). Distribution was limited to subscribers to the Journal. The second edition is planned for publication in mid 2001 in time for distribution at IZC-13 (Montpellier, July 2001).

The format for the second edition is largely unchanged from the first. The intended audience is still the applications researcher, reasonably skilled in the art, who wants a particular phase enough to attempt its synthesis in the laboratory. In practical terms, this means approximately first year graduate students. With the exception of organic templating agents, zeolite synthesis does not require elaborate equipment or expensive reagents. As evidenced by the contributors list, many investigators in many different countries have been active in the synthesis field.

The current edition has reprinted all the recipes from the first edition plus 24 new recipes. The introductory articles on basic skills in zeolite synthesis includes the articles from the first edition (some with substantial revisions) plus five new articles. The XRD patterns have been recorded using different instrument settings from those in the first edition and are intended to conform to typical X-ray diffraction practice. In most cases, only the XRD pattern for the product as synthesized is printed here. The exceptions are those phases which show marked changes in the XRD pattern upon calcination.

Zeolite synthesis is an active field of research. As long as this continues, new phases will be discovered and new techniques for preparing existing phases will appear. The IZA Synthesis Commission hopes to continue and enlarge this collection to include all phases of interest to the zeolite research community.
