ABSTRACT:
A ferrite having a substantially continuous range of grain sizes in a substantially uniform distribution throughout the range of grain size, wherein no single grain size represents more than approximately 10% of the total grains. A method of forming a ferrite is disclosed wherein a first composition which yields a first grain size range upon sintering is combined with a second composition which yields a second different grain size range upon sintering to form a composite, and the composite is sintered to form the ferrite which exhibits a relatively temperature stable behavior within an extended temperature range.
