“…Longer duration in the synthesis process may result in more of the 312 phase, and is worth exploring. The RT LPs of Ti 3 SnC 2 ( a = 3.13543 (6) Å, c = 18.6074 (5) Å) matched quite well with previously reported values, as well as those determined for sample B (see below). A comparison between the a and c LPs, elastic constants, and Young's moduli of Ti 3 SnC 2 and Ti 2 SnC from this work, and previous studies, is compiled in Table .…”

“…Ti 2 SnC was also studied as a binder in diamond composites for cutting tools . The 312 Sn‐containing phase, Ti 3 SnC 2 , was reported for the first time in thin film by Högberg et al It is important to note that, currently, only six 312 MAX phases have been synthesized: Ti 3 SiC 2 , Ti 3 GeC 2 , Ti 3 AlC 2 , Ti 3 SnC 2 , V 3 AlC 2 , and Ta 3 AlC 2 , excluding solid solution mixtures . Bulk Ti 3 SnC 2 was discovered accidentally by Dubois et al during the synthesis of Ti 2 SnC when Fe, introduced from the steel container, nucleated the 312 phase.…”

Herein, we report—for the first time—on the additive‐free bulk synthesis of Ti3SnC2. A detailed experimental study of the structure of the latter together with a secondary phase, Ti2SnC, is presented through the use of X‐ray diffraction (XRD), and high‐resolution transmission microscopy (HRTEM). A previous sample of Ti3SnC2, made using Fe as an additive and Ti2SnC as a secondary phase, was studied by high‐temperature neutron diffraction (HTND) and XRD. The room‐temperature crystallographic parameters of the two MAX phases in the two samples are quite similar. Based on Rietveld analysis of the HTND data, the average linear thermal expansion coefficients of Ti3SnC2 in the a and c directions were found to be 8.5 (2)·10−6 K−1 and 8.9 (1)·10−6 K−1, respectively. The respective values for the Ti2SnC phase are 10.1 (3)·10−6 K−1 and 10.8 (6)·10−6 K−1. Unlike other MAX phases, the atomic displacement parameters of the Sn atoms in Ti3SnC2 are comparable to those of the Ti and C atoms. When the predictions of the atomic displacement parameters obtained from density functional theory are compared to the experimental results, good quantitative agreement is found for the Sn atoms. In the case of the Ti and C atoms, the agreement is more qualitative. We also used first principles to calculate the elastic properties of both Ti2SnC and Ti3SnC2 and their Raman active modes. The latter are compared to experiment and the agreement was found to be good.

“…They characterized the reaction route by five main reactions [6] that are treated in detail below. Using HIP, Dubois et al [11] were able to produce a Ti 3 SnC 2 -based material starting from a 2:1:1 elemental powder mixture stoichiometry. At elevated temperatures, most MAX phases degrade by dissociation into the A element and a remaining MX x part.…”

“…Together with the annealed Mo 2 GaC + Fe sample, where the Mo 2 GaC phase remains intact and shows no indication of the Ga being substituted, it is clear that Au has an important role for catalyzing the reaction of Fe, while being a less competitive substituent than Fe. Formation of the MAX phases assisted by an additional element has been reported in, for example, the synthesis of Ti 3 SnC 2 , which is difficult to form in bulk without the addition of Fe [30,31]. Other examples can be found in the MAX phase synthesis with transition metal hydrides as a starting material [32][33][34].…”

The first Fe-based MAX phase is realized by solid-state substitution reaction of an Fe/Au/Mo 2 GaC thin-film diffusion couple, as determined by X-ray diffraction and scanning transmission electron microscopy. Chemical analysis together with elemental mapping reveals that as much as 50 at.% Fe on the A site can be obtained by thermally induced Au and Fe substitution for Ga atomic layers in Mo 2 GaC. One-sixth of the original Ga is also replaced by Au atoms. When annealing Mo 2 GaC thin films covered with Fe only, the Mo 2 GaC phase remains intact, that is, Au acts as a catalyst for the substitution reaction. IMPACT STATEMENT The first direct evidence showing Fe-containing MAX phase, Mo 2 AC, with Fe ∼ 50 at.% on the A sites is presented, synthesized by thermally induced Fe and Au substitution reaction catalyzed by Au.
