发明名称 Process of preparing ferrite with a predetermined ferrous content.
摘要 <p>Process of calcining and ball milling Manganese Zinc MnZn, ferrite material for achieving a ferrite having a ferrous iron content appropriate for optimum magnetic properties. The process includes a controlled atmosphere, time, and temperature for the calcining process step, and a controlled ball milling step overtime where the interaction of the stainless steel balls and milled slurry contributes to final ferrous iron content. These two process steps are balanced yielding a MnZn ferrite of a predetermined particle size with a controlled ferrous iron content which is a function of both the calcining and ball milling steps.</p>
