Synthesis of the new max phase zr2alc
WebFeb 9, 2016 · Here we report on attempts to synthesise quaternary MAX phases (Zr,M) 2 AlC and Zr 2 (Al,A)C where M = Cr, Ti or Mo and A = S, As, Sn, Sb and Pb. We were notably able to produce Zr 2 (Al 0.2 Sn 0.8 )C, Zr 2 (Al 0.35 Pb 0.65 )C, and Zr 2 (Al 0.3 Sb 0.7 )C, with the latter representing the first antimony-based MAX phase ever reported.

WebThe lattice parameters were determined and confirmed by high-resolution transmission electron microscopy. The effect of varying the synthesis temperature was investigated, indicating a relatively narrow temperature window for the synthesis of Zr2AlC. ZrC was always present as a secondary phase by hot pressing in the 1475-1575 degrees C range. WebThe synthesis route of Zr2AlC MAX phase-based ceramics was reported elsewhere [14]. In brief, fully dense Zr2AlC ceramics have been synthesized by reactive hot pressing of ZrH2, Al and C powders (Zr:Al:C 2:0.8:1.2 or 2:1.1:0.95). XRD analysis of the Zr2AlC ceramics showed that they comprised 67 wt% Zr2AlC and 33 wt% ZrC [14].
WebFeb 9, 2016 · Abstract. Despite having never been synthesized, the MAX phase Zr 2 AlC attracts a lot of interest owing to its foreseen properties.
