Spark Plasma Sintering of Negative Temperature Coefficient Thermistor Ceramics

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...

In-situ Fabrication of Transparent Magnesium Aluminate Spinel by Spark Plasma Sintering

Transparent polycrystalline spinel ceramic was fabricated without any sintering aids by spark plasma sintering method of a mixture of Al2O3 and MgO powders for only 10min soak at 1250°C. Densification, microstructure and optical transparency of spinel were examined. The spinel exhibits an in-line transmission of 55% for a visible-wavelength of 470nm and high hardness value of 2040 HV.

Comparison of Creep Behavior in Alumina Based Ceramics Densified by Spark Plasma Sintering and Hot Pressing

Spark plasma sintering (SPS) method, as plasma activated sintering, is a method applicable for rapid sintering of metals and ceramics. Owing to the advantage of rapid heating, the alumina ceramics obtained by SPS have a grain size and density comparable to those of hot pressed ones. The increase of densification rate may be related to some difference in ion transport characteristics. This study...
