摘 要：<正>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 A to 274（?）.The thermal properties indicate absorbed water still remain at low temperature,crystalline wate will be decomposed from 230℃to 260℃,partial Mn²⁺will be oxidized near 730℃.TEM shows the ferrite particles pocess a spherical morphology and uniform nanosize.
