【Abstract】 The process of self-propagating high-temperature synthesizing SrFe 12O 19 composite was investigated. The constituent phases magnetic properties of the composites were investigated by means of X-ray diffraction (XRD) and vibrating sample magnetometer (VSM),H c:204.8 kA/m,M s:12.47 emu/g. The results showed that the SrFe 12O 19 composite by SHS was highly pure and possessed good magnetic properties. This paper also introduces some facts affecting the composite in the process of SHS.更多还原
