Fabrication of Paper‐Derived Ti3SiC2‐Based Materials by Spark Plasma Sintering
Advanced Engineering Materials, 2020Novel paper‐derived Ti3SiC2‐based ceramics are fabricated by spark plasma sintering (SPS). A Ti3SiC2‐loaded preceramic article is used as feedstock. The sintering temperature and pressure are 1100–1200 °C and 20–50 MPa, respectively.

Intergranular alumina–SiC micro-nanocomposites sintered by spark plasma sintering
Materials Chemistry and Physics, 2010Alumina-5 vol% SiC micro-nanocomposites with almost completely intergranular microstructure were produced by spark plasma sintering (SPS). Before sintering, well dispersed slurries were obtained by ball-milling of powders using an electrosteric dispersant in aqueous media. High density composites could be achieved at lower sintering temperatures by SPS,

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.

Sintering of Soda‐Lime Glass Microspheres Using Spark Plasma Sintering
Journal of the American Ceramic Society, 2011Sintering experiments on soda‐lime glass microspheres have been performed using spark plasma sintering in the temperature range 485°C–560°C. Samples with relative densities between 64% and 99.6% have been obtained in about 10 min. For almost fully dense samples, the microstructure exhibits an unusual “interface‐like” aspect for a glass.

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.

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.

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 as advanced PM sintering method
Powder Metallurgy, 2002AbstractA short overview of works on spark plasma sintering (SPS) is given in the present paper. SPS is a newly developed rapid sintering technique with a great potential for achieving fast densification results with minimal grain growth in a short sintering time.
