The effect of sintering parameters on spark plasma sintering of B4C
Ceramics International, 2017Abstract The effects of sintering temperature, heating rate, and holding time on the density and hardness of the spark plasma sintered B4C were investigated. Experimental results are compared with the predictions from computational thermodynamics.

Performances of CaSiO3 ceramic sintered by Spark plasma sintering
Materials Characterization, 2008Abstract Wollastonite (CaSiO3) ceramics were prepared by a new sintering technology: spark plasma sintering (SPS), using CaSiO3 ultra-fine powders as precursor. The ceramics were sintered at different temperature and different heating rate. The properties of sintered ceramics were discussed detail.

Spark Plasma Sintering of Zirconium Diborides
Journal of the American Ceramic Society, 2008The densification behavior and grain growth of single‐phase ZrB 2 ceramics by a spark plasma sintering (SPS) process were systematically investigated. The sintering was conducted at temperatures ranging from 1800° and 1950°C in vacuum under a pressure of 50 MPa.

Spark plasma sintering of tantalum carbide
Scripta Materialia, 2010A tantalum carbide powder was consolidated by spark plasma sintering. The specimens were processed under various temperature and pressure conditions and characterized in terms of relative density, grain size, rupture strength and hardness. The results are compared to hot pressing conducted under similar settings.

Advancement of Tooling for Spark Plasma Sintering
Journal of the American Ceramic Society, 2015A combined experimental and numerical study is conducted to investigate temperature nonhomogeneities within a Spark Plasma Sintering tooling setup. Radial thermal gradients through a powder compact are encountered, a cause of microstructural nonuniformities in sintered specimens, which tend to become more significant when increasing the setup's ...

Numerical Simulation of Spark Plasma Sintering
Advances in Science and Technology, 2010A macro-scale model of spark plasma sintering (SPS) that couples electrical, thermal, stress-strain and densification components is presented. The continuum theory of sintering is incorporated enabling the evolution of the densification based on local conditions, thus a true spatial density distribution could be obtained. Specimen behavior is described

Spark plasma sintering of transparent alumina
Scripta Materialia, 2007Transparent alumina with a fine grain size (0.27 μm) was obtained by controlling the heating rate during spark plasma sintering processing. The alumina sintered at 1150 °C with a heating rate of 8 °C/min has a residual porosity of 0.03% and an in-line transmission of 47% for a wavelength of 640 nm.

Analysis of Mechanisms of Spark-Plasma Sintering
Key Engineering Materials, 2008Spark-Plasma Sintering (SPS) involves rapid heating of powder by electric current with simultaneous application of external pressure. Numerous experimental investigations point to the ability of SPS to render highly-dense powder products with the potential of grain size retention.
