ABSTRACT:
Aluminophosphate-based molecular sieve compositions having the crystal structure of AlPO.sub.4 -54 are stabilized against framework collapse or conversion to other crystal structures by treatment in their hydrated state with boric acid or salts thereof. The stabiized products are characterized, in addition to their essential AlPO.sub.4 -54 structure, by the presence of at least 6 ppm of extraneous boron.
