D-15,444, ABSTRACT OF THE DISCLOSURE, The invention involves composite structures of multiple phases, at least two of which are inorganic crystalline compositions that are contiguous and have a common crystal framework and structure and at least one of, them contains phosphorus and aluminum atoms as part of its crystalline framework structure; and to processes for making the same. It is desired that each phase has a microporous molecular sieve structure. The process involves the growth of a crystalline structure constituting such a phase in the presence of crystals of another of such a phase. Preferably, the process involves a hydrothermal crystallization treatment of the precursors to such …
