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.254-259openAccesssinteringferritesiron oxidesthermal analysisdilatometryceramicsArtigo de periódico80510.4028/www.scientific.net/MSF.805.254https://orcid.org/0000-0002-5172-5082
