Ferrite multiphase/carbon nanotube composites sintered by microwave sintering and spark plasma sintering

Characterization of Multiwalled Carbon Nanotube-Reinforced Hydroxyapatite Composites Consolidated by Spark Plasma Sintering

Pure HA and 1, 3, 5, and 10 vol% multiwalled carbon nanotube- (MWNT-) reinforced hydroxyapatite (HA) were consolidated using a spark plasma sintering (SPS) technique. The relative density of pure HA increased with increasing sintering temperature, but that of the MWNT/HA composite reached almost full density at 900°C, and then decreased with further increases in sintering temperature. The relat...

Biomimetic apatite sintered at very low temperature by spark plasma sintering: physico-chemistry and microstructure aspects.

Nanocrystalline apatites analogous to bone mineral are very promising materials for the preparation of highly bioactive ceramics due to their unique intrinsic physico-chemical characteristics. Their surface reactivity is indeed linked to the presence of a metastable hydrated layer on the surface of the nanocrystals. Yet the sintering of such apatites by conventional techniques, at high temperat...

Magnetic enhancement of thermal conductivity in copper–carbon nanotube composites produced by electroless plating, freeze drying, and spark plasma sintering

Novel highly scalable carbon nanotube-strengthened ceramics by high shear compaction and spark plasma sintering

e report a new strategy, based on high shear compaction and spark plasma sintering, for the massive and low cost production of 100% dense eramics containing carbon nanotubes. Custom forming and stacking of flexible green sheets of record-breaking dimensions can yield an unlimited ange of three-dimensional structures. The strategy was successfully validated in the production of multi-walled carb...
