According to the influence of sintering time, sintering temperature, different amount of flux and different molar ratio of Fe / Sr to the magnetic properties of prepared SrFe12O19 magnetic particles, the optimum SrFe12O19 conditions were concluded. They are: sintering time: 3 hours; sintering temperature: 1073.15 k; flux NaCl amount: 15% wt of the reaction raw materials; Fe / Sr molar ratio: 11.4; the sample magnetic properties: Ms = 63.39emu / g; Mr = 33.44emu / g; Hc = 5798Oe, Mr / Ms = 1 : 1.90 ≈ 1:2. The prepared SrFe12O19 should be single crystal particles and in the shape of flake, and the particle size should be generally about 80-90nm with uniform distribution.
