description |
This research work is an initial step to produce manganese-zinc ferrites in
the laboratory using the solid-state ceramic preparation method with controlled
atmospheres. The first part of the work was to develop the required material by
manipulation of composition. Then, the specimens were sintered at 1350°C in an
oxygen partial pressure. At this stage, a systematic crucial approach was used to
produce high permeability ferrites with suitable oxygen partial pressure. This
involved a gradual introduction of nitrogen gas into the furnace during sample
cooling giving an optimum equivalent isocompositional line. This work has
successfully produced materials (samples MRQI and MRQ2) suitable with the
permeability in the range of 2000 to 2500 when an average particle size was
reduced to ~2.5µm and zinc oxide was added to minimize zinc loss. Then the
sintering cycle was made to follow the isocompositional line In conclusion an optimum processing technique has been established for
producing ferrite materials with the desired magnetic properties. |
