Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. Powders were characterized with XRD, SEM and particle seizer. Subsequent heating was monitored on TGA/DTA in air atmosphere. After compaction of the milled powders, sintering was also performed in a dilatometric device. Sintered specimens were characterized microstructurally with SEM on a fresh breakage. Ferrite powders changed with milling as well as with second run heating are characterised to approach the possible best ratio of the milling and heating that should be used to obtain desired micrstructure.
