| Abstract: | The AlPO4-5 molecular sieve was synthesized hydrothermally in the presence of organic amine (Pr3N) as the template.A systematic investigation was made into the effects of conditions for hydrothermal crystallization,amount of template(Pr3N),PH value of reactive mixture.crystallization time and crystallization temperature etc.,on the formation of AlPO4-5 molecular sieve and crystallinity of the product.The structure and properties of AlPO4-5 were characterized by means of XRD,IR,SEM,DTA and TG. |
