Abstract

Quaternary MAX phases, (Ta1-xTix)3AlC2 (x = 0.4, 0.62, 0.75, 0.91 or 0.95), have been synthesised via pressureless sintering of TaC, TiC, Ti and Al powders. Via chemical etching of the Al layers, (Ta0.38Ti0.62)3C2Tz-a new MXene, has also been synthesised. All materials contain an M-layer solid solution of Ta and Ti, with a variable Ta concentration, paving the way for the synthesis of a range of alloyed (Ta,Ti)3C2Tz MXenes with tuneable compositions for a wide range of potential applications.
