Synthesis of Mn _xZn_(1−x)Fe₂O₄ nanoparticles by ball-milling hydrothermal method

Abstract

SMn _xZn_1−xFe₂O₄ (x=1,0.9,0.8,0.7,0.6,0.5,0.25,0) nanoparticles were prepared by ball-milling hydrothermal and investigated by X-ray diffraction, DTG and TEM. Nanocrystallite grain size was determined by X-ray linewidth to be from 63 Å to 274 Å. The thermal properties indicate absorbed water still remain at low temperature, crystalline wate will be decomposed from 230 °C to 260 °C, partial Mn²⁺ will be oxidized near 730 °C. TEM shows the ferrite particles pocess a spherical morphology and uniform nanosize.
