Low Loss of Fine Grained Mn-Zn Ferrite

Abstract
Mn-Zn ferrite with grain size of 1.5µm was obtained by sintering hydrothermal-precipitated powders with uniform dispersion of additions. The fine grain size and high density were realized simultaneously by the use of fine particle ferrite powder and fine particle additives, planetary ball mill mixing of MnZn ferrite powder and additives and low temperature sintering. The core loss of a newly developed ferrite with fine grain was significantly reduced to that of a commercial ferrite.
