Large crystals of the molecular sieve AIP04-5 up to 920 pm in !en th have been rown during hydrothermal synthesis by using trtethylamine as a templating agent. The yieldlof the AIP04-5 $as, is within a range of 50 -60%.
AlPO 4 -11 nanocrystals, 0:05 Γ 0:08 lm in size, were synthesized by optimizing the following chemical parameters: the crystallization temperature and time, the H 2 O content, the molar ratio of phosphorus to organic template (P 2 O 5 /R), and the HF content. The products were characterized by powde
