FERRITES, MAGNETIC, H.F.

Abstract

The approach to the work was split into two directions based on the grain size of the sintered ferrite. One direction involved a study of ferrites with grains which are relatively inhomogeneous and range in size from 1 micron to more than 100 microns. The second direction involved a study of ferrites with a relatively homogeneous grain structure, with grains ranging from 1 micron to 3 microns. The two directions are distinguished by calling the ferrites produced either coarse-grain ferrites or fine-grain ferrites, respectively. The report is presented in two parts: Part I concerns Mn-Zn Ferrites and Part II concerns Ni-Zn Ferrites. Each part has a section A and a section B. Section A concerns coarse-grain materials and section B concerns fine-grain materials. There are four primary steps in the ceramic preparation of a ferrite: calcining, milling, pressing and sintering. Through the years a more or less standard procedure has been developed for the first three of these steps and the sintering schedule has been used as the principle variant. (Author)
