✦ Synopsis

AlPO 4 -11 nanocrystals, 0:05 Â 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 powder X-ray diffraction and scanning electron microscope. AlPO 4 -11 nanocrystals could not be obtained by optimizing only the crystallization temperature, time and the water content, but obtained by optimizing the molar ratio of P 2 O 5 /R, the organic template, and the HF content.
