Abstract

Abstract: Nanocrystalline MgAl2O4 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 600°C and 700°C. The average crystallite size of calcined powder at 800°C for 2h was in the range of 8-12nm. In addition, SEM micrograph showed that the synthesized powder had a spherical morphology.
