Abstract

Abstract : Despite having never been synthesized, the MAX phase Zr2 AlC attracts a lot of interest owing to its foreseen properties. A possible way to circumvent this obstacle is to stabilize Zr2 AlC by partially substituting one of its constituting elements. Here we report on attempts to synthesise quaternary MAX phases (Zr, M)2 AlC and Zr2 (Al, A)C where M = Cr, Ti or Mo and A = S, As, Sn, Sb and Pb. We were notably able to produce Zr2 (Al0.2 Sn0.8 )C, Zr2 (Al0.35 Pb0.65 )C, and Zr2 (Al0.3 Sb0.7 )C, with the latter representing the first antimony-based MAX phase ever reported. Impact Statement : Numerous syntheses of Zr2 AlC derived compositions were attempted. Zr2 (Al0.2 Sn0.8 )C, Zr2 (Al0.35 Pb0.65 )C and Zr2 (Al0.3 Sb0.7 )C were notably produced and reported for the first time.
