NiCuZn ferrite powders were prepared by self-propagating high temperature synthesis(SHS) using carbon powder with different mass fractions as fuel.The prepared NiCuZn powder was firstly pressed into a ring and then sintered.The effect of carbon content in the raw materials on the phase composition,microstructure,density and magnetic property of the NiCuZn powders was investigated via X-ray diffractometer,scanning electron microscope,vibrating sample magnetometer and impedance analyzer,respec-tively.The resu...

自蔓延高温合成(self-propagating high tempera-ture synthesis,SHS)反应合成的NiCuZn铁氧体粉体具有纯度高、烧结活性好的特点,并且反应速率快、能耗低,较传统工艺优势明显,因此具有较大的推广价值[1–5]。近年来对以Fe粉为燃剂SHS反应合成NiCuZn铁氧体粉体的研究报道较多,在
