Abstract
Aluminophosphate zeolites(AlPO4- tridymit) was prepared using aluminium hydroxide precursor as a source of alumina and triethylamine (TEA) as the structure directing agent via microwave technique. The influence of initial Aluminium- phosphorus ratio, microwave power and heating time on the dimensions of AlPO4- tridymit crystals formed in the system Al2O3:P2O5:(C2H5)3N has been studied systematically through powder XRD, SEM, EDAX and BET analysis. It was found that the crystallinity and morphology of the AlPO4- tridymit formed was depended on the initial Al- P ratio, microwave power and duration. High crystalline products were obtained with 1:1(Al:P) ratio while for 1:2 (Al:P) , the products obtained were slightly amorphous.
