Abstract

The preparation of high permeability manganese zinc ferrous ferrites is rather complicated and if one is to achieve high permeability and the other essential electrical characteristics of low losses, low temperature coefficient, relatively high specific resistivity, etc., quality controls at various stages of processing is essential. The microstructure of the sintered samples do have considerable influence on the electrical properties. The microstructure and the electrical properties of many specimens are correlated with raw material purity, firing conditions such as atmosphere, oxygen content, temperature of soaking, etc.
