It is possible to work on the representation of Sr / Fe hard ferrites on a wide sintering level. CIRCOLIT® is well dispersible in the Sr/FeO system.
A targeted integration of the elementary magnets is prevented due to the formation of glass phases in the sintering process. In addition, the release of Sr from the elementary magnets s is prevented by the presence of Ca fraction.
