Resumo
Cobalt and cobalt-manganese spinel ferrites have magnetostrictive properties suitable for
application in magneto-electric and magneto-mechanical transducers. In this work, coppersubstituted
ferrites of these compositions were processed by means of the ceramic method and their
sinterabilities were evaluated by dilatometric thermal analyses. The results obtained suggest that
copper affects the solid-state reactions for the spinel formation and lowers the required sintering
temperature for the ferrites. However, the densification obtained with sintering of the coppersubstituted
ferrites at 950 oC for 6h was only 64%, which indicates that further adjustments on the
processing route must be made in order to obtain higher densities.
