| description |
This research work was conducted to investigate and understand better
the characteristics of magnesium based ferrites. Magnesium-based ferrites were
chosen due to one of their vital characteristics, that is high electrical resistivity,
which can make them better materials at higher operating frequencies. Besides,
they have a lower production cost and no environmental effect. Therefore,
perhaps, they can be a better substitute to the existing technological ferrites and
consequently replacing them. In order to achieve these goals, a wide-scope
experimental investigation was conducted . The samples were prepared by the
oxide ceramic processing method, involving dry mixing and solid state reactions.
The experimental investigation covered the effects of compositional variations in
magnesium-based ferrites with iron deficiency, excess zinc, iron deficiency with
excess zinc, magnesium-zinc ion exchange and magnesium-iron ion exchange.
Additional experimental work was also carried out to study the effects, on
microstructure, of the grinding time, pre-sintering temperature, sintering
temperature and sintering time. It was found that, in general, iron deficiency and
excess zinc was beneficial to obtaining good magnetic properties. For the
magnesium-zinc and magnesium-iron ion exchange, there existed particular
compositions which yielded optimum magnetic properties. |
