Octahedral manganese trioxide was prepared from manganese sulfate solution with air as oxidant and compound additive as pH regulator. The results showed that the product had high crystallinity, stable baseline and significant diffraction peak. The micro morphology was formed by stacking regular octahedral structure, the particle size was uniform, and it was about 200nm, the pores were rich, the specific surface area was 6.5 m 2 /g, and the tap density was 2.11g/cm 3 . All performance indexes of the product met the excellent standard of soft ferrite manganese trioxide (GBT21836-2008).
