How to overcome the main challenges of SPS technology: Reproducibility, multi-samples and elaboration of complex shapes.

Study of the densification and grain growth mechanisms occurring during spark plasma sintering of different submicronic yttria-stabilized zirconia powders

“…Finally, the activation energy Q d of the densification mechanism can be calculated by plotting (6):…”

“…Spark Plasma Sintering (SPS) is an advanced technique with a high potential for the processing of materials with tailored properties [5]. Recently, SPS has experienced a technological leap with the development of a methodology for developing materials with 3D complex shapes [6]. This considerable advance has been made possible by the development of reliable digital tool, in which densification and grain growth mechanisms have been implemented, to simulate the densification of a complex shape by SPS [7].…”

Hierarchically porous and mechanically stable monoliths from ordered mesoporous silica and their water filtration potential

“…17 Initial restrictions of the SPS process, such as scalability or structural limitations, have been overcome by the development of multi-sample dies, machinable parts, and semi-continuous systems. 18,19 While one focus of SPS remains on the densification of conventional and hard-to-sinter materials, recently, the production of porous products came into focus. 20,21 SPS was previously applied to fabricate porous OMS monoliths from sol–gel derived SBA-15 powder, 22,23 mesoporous spherical particles, 24 and hydrothermally produced OMS.…”
