摘      要：This paper reports on the effect of precursor gel preparation on the microstructural formation of aluminophosphate-5(AlPO4-5) molecular sieves in the hydrothermal *** morphology of AlPO4-5 crystal changed from sphere to ellipse with two symmetrical craters when the aluminophosphate precursor gel was prepared via dropwise addition of acid and TEA under strong stirring,and continuous stirring overnight during the gel aging *** results also showed that both of well-crystallized spherical and elliptical AlPO4-5 crystals covered by the fibrous crystals could be hydrothermaily synthesized at 150℃for 4 h or *** average particle size of spherical AlPO4-5 samples was about 35-45μm in diameter,whereas the elliptical AlPO4-5 exhibited approximately 13μm in width and 15μm in length.
