Fabrication of ultrafine-grained alumina ceramics by two different fast sintering methods

Fundamental Aspects of Spark Plasma Sintering: I. Experimental Analysis of Scalability

“…In fact, alumina was one of the most intensively analyzed materials in the framework of previously conducted SPS studies . Most publications in this area were dedicated to the analysis of mechanical or optical properties of spark plasma‐sintered alumina specimens.…”

“…Most publications in this area were dedicated to the analysis of mechanical or optical properties of spark plasma‐sintered alumina specimens. Some studies considered the impact of various process parameters on the alumina densification kinetics during SPS, and a limited number of works included modeling of the constitutive behavior or macroscopic modeling of the coupled phenomena occurring during SPS of alumina powder …”

“…Most publications in this area were dedicated to the analysis of mechanical [14][15][16][17][18]20,22,25,27,38 or optical 23,24,[30][31][32][34][35][36]39,44 properties of spark plasma-sintered alumina specimens. Some studies considered the impact of various process parameters on the alumina densification kinetics during SPS, 21,26,28,29,37,[40][41][42][43] and a limited number of works included modeling of the constitutive behavior 21,37,41 or macroscopic modeling of the coupled phenomena occurring during SPS of alumina powder. 33 To ensure the rigorousness of the scalability analysis, the shape of the specimens and the tooling is maintained the same (i.e., the cylindrical specimens' height-to-radius aspect ratio is the same, etc.…”

Advanced Manufacturing of Hard Ceramics

“…SPS is a powerful tool to produce extremely fine-grained materials not accessible by other processes. The feasibility of SPS processes has been demonstrated for Si 3 N 4 and SiC as well as for alumina (Guillard, 2007;Meng, 2011;Nishimura, 2007).…”
