Nanostructured CoSi Obtained by Spark Plasma Sintering
Journal of Electronic Materials, 2015Cobalt monosilicide is a cheap, environmentally friendly thermoelectric material for medium temperatures (200–700°C). While its power factor is similar to the state-of-the-art thermoelectric materials, its thermal conductivity is too large to reach high ZT values.

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.

Ceramics International, 2015
Abstract The spark plasma sintering (SPS) of mullite powder (D50=3.29 μm) was investigated. The SPS parameters such as the dwell temperature, applied external pressure, and dwell time were varied. The sinterability of mullite increases with increase in the dwell temperature, dwell time and applied external pressure.

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.

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
