Experimental of Ti3AlC2

A mixture of NaCl and KCl in eutectic (supplied by Tianjin Kemiou Chemical Reagent Co., Ltd. Analytical grade) was used as a liquid medium, which was firstly dried at 350°C for 24 h to remove moisture. A 1.63 g mixture composed of commercially available powders of Ti (1.20 g, particle size 99.8%), Al (0.23 g, particle size 99.8%), and acetylene black (0.20 g, particle size 99.9%) with a molar ratio of 3Ti/1Al/2C were used as precursor materials, which were weighed and mixed with various mass ratios of the dried NaCl–KCl of 1:1, 1:3, 1:6, and 1:10 in an alumina crucible, respectively. After that, the alumina crucible was placed in a closed stainless steel vertical tubular reactor and subsequently heated to 950◦C holding for five h or 1000◦C holding for two h at a rate of 6°C·min−1 under flowing argon (30 mL·min−1, purity >99.999%). After prior thermal exposures, the chamber was naturally cooled to room temperature. Then the sample was ultrasonically rinsed with boiling deionized water several times to remove residual salts. Finally, the obtained sample was dried at 80°C for 12 h for characterization. The phase constituents of samples were identified by X-ray diffraction (XRD, PANalytical X'Pertpro) with Cu target Kα radiation. The sample's morphology was characterized by high-resolution transmission electron microscopy (HRTEM, FEI Tecnai G2 F20) and selected area electron diffraction (SAED). The microstructure of the sample was also characterized by field emission.
