Hot Pressing: Technology and Theory
Hot pressing is the densification of a loosely packed powder or a compacted preform by the simultaneous application of heat and pressure. The specific benefits of hot pressing are seen in terms of the achievement of high final density and microstructural improvement such as fine grain size (see Fig. 1).Hot-pressing procedures include simple …

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.
