Influence of cold isostatic pressing on the magnetic …

We propose to use Ni 0,30 Zn 0,57 Cu 0,15 Fe 2 O 4 ferrite and to compress it by cold isostatic pressing (CIP) into a a green ceramic block and to machine it to obtain the desired ICT of complex shape prior sintering. We compare the magnetic permeability spectra and hysteresis loops the CIP and uniaxially pressed ferrites.
