Large-scale　production　of　strontium　hexaferrite　(SrFe12O19)　particles　was　successfully　achieved　by　molten-salt-assisted　coprecipitation.　A　mixture　of　sodium　hydroxide　and　sodium　carbonate　was　served　as　mixed　precipitant　to　obtain　ferrite　precursors.　The　effects　of　the　Fe3+/Sr2+　molar　ratio,　calcination　temperature,　calcination　time,　and　molten-salt　amount　on　the　formation,　morphology　and　magnetic　properties　of　SrFe12O19　particles　were　investigated.　The　resultant　particles　were　characterized　by　Fourier　transform　infrared　spectroscopy,　thermogravimetric　analysis,　X-ray　diffraction,　scanning　electron　microscopy,　and　vibrating　sample　magnetometer.　Single-phase　SrFe12O19　particles,　with　particle　sizes　of　0.8-1.2　mu　m,　were　obtained　from　the　precursor　(with　a　Fe3+/Sr2+　molar　ratio　of　10)　being　calcined　at　950　degrees　C　for　2　h　using　the　mass　ratio　(NaCl　to　precursor)　of　0.3.　The　saturation　magnetization,　remanent　magnetization　and　coercivity　were　about　62　emu/g,　37　emu/g,　and　4310　Oe,　respectively.　A　comparison　of　the　products　obtained　at　different　preparation-scales　was　also　done.　The　results　showed　that　it　was　easier　to　control　the　particle　morphology　using　molten　salt　synthesis　and　more　economical　on　a　large-scale　production.　(C)　2014　Elsevier　B.V.　All　rights　reserved.
