Recent Advances in Techniques for Characterizing Zeolite Structureslications. By analogy with the properties of zeolites for which structures are known (of which there is a large and growing data base), possible applications for a new zeolite can be identified once its essential structural features are known. Structural details at several degrees of precision and o
