MnZn ferrite granules were made under different conditions. By using these granules, effect of water content on the compaction behavior has been studied. The granules were characterized by strength, deformation modulus, apparent density and flow rate. The relationship between compacting pressure and intergranular pores has been studied. It was found that the compaction behavior was affected mainly by water content, and that the bending points were observed in the graphs of pressure and compaction density. The reason for these bending points was considered by pressure between upper punch and lower punch was decreased when increasing of water content. Water resulted in amelioration of pressure transmission.
