Abstract:
Abstract: Nanocrystalline MgAl۲O۴ spinel powder was synthesized using metal nitrates and a
polymer matrix-based composed of sucrose and polyvinyl alcohol (PVA). The precursor and the
calcined powders were characterized by simultaneous thermal analysis (STA), X-ray diffraction
(XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy
(SEM). According to XRD results, the inceptive formation temperature of spinel via this technique
was between ۶۰۰°C and ۷۰۰°C. The average crystallite size of calcined powder at ۸۰۰°C for ۲h
was in the range of ۸-۱۲nm. In addition, SEM micrograph showed that the synthesized powder had
a spherical morphology.
