摘要: Abstract The Sr-ferrite powders, SrFe 12 O 19 , were synthesized by the molten salt method using ( NaCl + KCl ) mixture. Particle morphology was homogeneous and hexagonal platelet like. Both particle size thickness increased as reaction temperature time increased. sintering density of magnet prepared with powders showed maximum value at 1200 ∘ C . magnetic properties investigated various temperatures. values remanent magnetization σ r 45 emu/g) coercivity field H c j 298 kA/m) occurred temperatures 1150– a higher than those same starting materials conventional ceramic process.
