Evaluation of the sinterability of copper-substituted ferrites by means of dilatometric thermal analysis
2015 - BRITO, VERA L.O. de; CUNHA, STEPHANIE A.; UCHOAS, ANA P.R.; ARAUJO, FABIANA F. de; NUNES, CRISTINA B.; GENOVA, LUIS A.
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.
Influence of Zn and Mg doping on the sintering behavior and phase transformation of tricalcium phosphate based ceramics
2015 - KAI, KAREN C.; MACHADO, CARLOS A.V.A.; GENOVA, LUIS A.; MARCHI, JULIANA
β-tricalcium phosphate based ceramics (β-TCP) are resorbable biomaterials used as bone substitutive materials. Several ions can substitute specific Ca positions in the crystalline structure of TCP, so that general Me-TCP can be obtained. Particularly, magnesium can increase the temperature of β-α-TCP transformation while zinc stimulates the bone formation. In this work, the influence of magnesium or zinc ions on the sintering behavior of Me-TCP was investigated. The powders were produced through wet chemical synthesis with a freeze drying process. The powders were calcined and subsequently uniaxially pressed into pellets. The pellets were sintered up to 1300°C/1h. The influence of Mg or Zn doping was investigated by dilatometric studies, thermal analysis and XRD. The microstructure was evaluated through SEM. The results suggest that Mg increased temperature of β-α-TCP phase transformation. The Me-doped TCP samples can be considered as promising biomaterials, having stimulatory effect of Zn or suitable densification due to Mg addition.
