Sumario:The first demonstration of plasma-flash sintering (PFS) is presented in this work.PFS is performed under a low-pressure atmosphere that consecutively generatesplasma and flash events. It is shown, by using several combined characterizationtechniques, that PFS stabilizes metastable phases on the surface of the material,which may be partially, but not solely, attributed to the generation of oxygenvacancies, and induces the absorption of ionized species, if a reactive atmo-sphere is employed. Even though additional research is required to understandthe fundamentals of PFS, it is evidenced its potential to be used as a material sur-face engineering tool, which may widen the technological capabilities of flashsintering
