A novel Multi‐Phase Flash Sintering (MPFS) technique for 3D complex‐shaped ceramics. Applied Materials Today, 26 (March), 101274. https://doi.org/10.1016/j.apmt.2021.101274.2352-9407https://hdl.handle.net/11441/141351This work demonstrates the first proof-of-concept of Multi-Phase Flash Sintering (MPFS). This novel tech- nique essentially consists of applying a rotating electric field to the sample by means of a multi-phase voltage source as furnace temperature increases. Several ceramic materials with different types of elec- trical conductivities are sintered within seconds at furnace temperatures much lower than those used for traditional DC flash sintering due to the higher power densities administered by a multi-phase power supply. Thus, ceramic materials are flashed at relatively lower applied voltages which minimizes un- desired phenomena such as localization and preferential current pathways. Furthermore, MPFS allows diverse electrode configurations to promote a more uniform electric field distribution, enhancing the sin- tering of 3D complex-shaped specimens. MPFS could be a true breakthrough in materials processing, as 3D complex-shaped specimens are homogeneously sintered at reduced temperatures, while keeping all the advantages of conventional flash sintering.application/pdf9 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Flash sinteringAlternating currentField-assisted sintering techniquesComplex shapeCeramic materialsYttria-stabilized zirconiainfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1016/j.apmt.2021.101274
