MXene compound having a novel crystalline morphology, and process for fabricating a compound of MAX phase type for synthesis of said MXene compound. The invention firstly relates to a MXene compound advantageously having a crystalline morphology that is mostly in tablet form which may be obtained from a MAX phase precursor obtained by spark plasma sintering process whereby the powders of the mixture are insulated, and to a process for fabricating the MXene compound. The invention also relates to compound of MAX phase type obtained by spark plasma sintering process whereby the powders of the mixture are insulated. The invention also relates to a synthesis process of an MXene compound from said precursor, and to the MXene compound thus obtained advantageously having a crystalline morphology that is mostly in tablet form.
A compound of general formula Mn+1XnTx, where n=1, 2 or 3, M is selected from among Ti, V Cr, Zr, Nb, Mo, Hf, Sc, Mn, Y and Ta, X is C or N, and where T corresponds to a terminal group selected from among the groups O, OH, F or any other halogen, S or any other chalcogen, characterized in that it is in the form crystals mostly having a general tablet shape, said tablets comprise two opposite parallel surfaces of defined length (L) spaced apart by a defined height (H), and in that:
A spark plasma sintering process to fabricate a compound of MAX phase type having the general formula Mn+1AXn, where n=1, 2 or 3, M is selected from among Ti, V, Cr, Zr, Nb, Mo, Hf, Sc, Mn, Y and Ta, A is selected from among Al, Si, P, S, Ga, Ge, As, Cd, In, Sn, Tl and Pb, and X is C or N, in a spark plasma sintering device (1) comprising a die (2) in graphite and two punches (3a,3b) in graphite defining a hollow chamber (4), characterized in that it comprises at least the steps of:
