Spark plasma sintering of BiFeO3

open access: yesMaterials Research Bulletin, 2009
Dense BiFeO3 ceramics were prepared by a novel spark plasma sintering (SPS) technique. The sintering was conducted at temperatures ranging from 675 to 750 8C under 70 MPa pressure. A bulk density value up to 96% of theoretical density was achieved in the process.

The absence of plasma in “spark plasma sintering” [PDF]

open access: yesJournal of Applied Physics, 2008
Spark plasma sintering (SPS) is a remarkable method for synthesizing and consolidating a large variety of both novel and traditional materials. There are a number of mechanisms proposed to account for the enhanced sintering abilities of the SPS process.

Densification and preservation of ceramic nanocrystalline character by spark plasma sintering [PDF]

open access: yes, 2012
Spark plasma sintering is a hot pressing technique where rapid heating by dc electric pulses is used simultaneously with applied pressure. Thus, spark plasma sintering is highly suitable for rapid densification of ceramic nanoparticles and preservation ...

Effect of 1 wt% LiF additive on the densification of nanocrystalline Y2O3 ceramics by spark plasma sintering [PDF]

open access: yes, 2011
Densification of nanocrystalline cubic yttria (nc-Y2O3) powder, with 18 nm crystal size and 1 wt% LiF as a sintering additive was investigated. Specimens were fabricated by spark plasma sintering at 100 MPa, within the temperature range of 700–1500 °C ...

Influence of pulse current during Spark Plasma Sintering evidenced on reactive alumina–hematite powders [PDF]

open access: yes, 2011
Spark Plasma Sintering (SPS) is increasingly used. The temperature and current are not independent parameters, making it difficult to separate the current intrinsic role from Joule heating.

Microstructure of Ba1−xLaxTiO3−δ ceramics sintered by spark plasma sintering [PDF]

open access: yes, 2011
Nano-sized Ba1−xLaxTiO3 (0.00 ≤ x ≤ 0.14) powders were prepared by a coprecipitation method and calcined at 850 °C in air. The corresponding ceramics were obtained by Spark Plasma Sintering (SPS) at 1050 °C.
