摘要：

Nanocrystalline MgAl2O4 is synthesized by citrate sol-gel process, which is characterized by high-temperature X-ray diffraction (HT-XRD), differential thermal analysis coupled with thermogravimetric (TG-DTA) and scanning electron microscopy (SEM). The precursor gel yields an amorphous oxide phase at 550 degreesC and begins to crystallize to the MgAl2O4 at 600 degreesC. The isoelectric point (IEP) of nanocrystalline MgAl2O4 is about pH 11.8.
