Preparation of MgAl2O4 by modified sol-gel method

Abstract

In this Study, Magnesium aluminate spinel (MgAl2O4) was prepared by modified sol-gel method. Magnesium oxide was dispersed in iso-propanol solution of aluminum sec-butoxide. Water has been added to promote gelation of alkoxide precursor. Dried samples were calcined at 300, 500 and 800degreesC and characterized by XRD, TGA and SEM methods.
