Well-dispersed nanocrystalline MnCr2O4 was prepared by a salt-assisted combustion process using low-toxic glycine as fuel and\nMn(NO3)2 and Cr(NO3)3\n?9H2O as raw materials. The obtained products were characterized by X-ray Diffraction (XRD), Fourier\nTransform Infrared (FT-IR) spectroscopy, Raman spectroscopy, Transmission Electron Microscopy (TEM), and Scanning Electron\nMicroscopy (SEM). The fabrication process was monitored by thermogravimetric and differential thermal analysis (TG-DTA). The\nphase formation process was detected by XRD, and MnCr2O4 single phase with high crystallinity was formed at 700?C. TEM and\nSEM images revealed that the products were composed of well-dispersed octahedral nanocrystals with an average size of 80 nm.\nInert salt-LiCl played an important role in breaking the network structure of agglomerated nanocrystallites.
