Abstract

Quaternary MAX phases, (TaxTi1-x)3AlC2 (x = 0.05, 0.1, 0.2, 0.33 or 0.5), have been synthesised via pressureless sintering of TaC, TiC, Ti and Al powders. Via chemical etching of the Al layers, (Ta0.38Ti0.62)3C2Tx – 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)3C2Tx MXenes with tuneable compositions for a wide range of potential applications.
