摘要
Hydrothermal crystallization of an aluminophosphate molecular sieve (AlPO4) has first been carried out from non-aqueous systems in the presence of templating agent,with the molarcomposition of the starting gel as 1.0Al2O3:5.0P2O5:10ethylenediamine: 180ethylene glycol. Aluminum triisopropoxideand phosphorous acid (85wt% H3PO4) were used exclusively assources for aluminum and phosphorous. The product has beencharacterized by means of X-ray Powder diffractiou (XRD),scanning electron microscopy (SEM), infrared (IR).spectrum,differential thermal analysis (DTA), thermogravimetric analysis(TG). etc.
