The particle size of the prepared Ti3AlC2 powder ranges from a few to dozens of micron

However, the particle size of the prepared Ti3AlC2 powder ranges from a few to dozens of microns. Meanwhile, it is reported that the initial particle size of Ti3AlC2 powder has a decisive influence on the kinetics of the selective extraction of Al from Ti3AlC2. In other words, decreasing the Ti3AlC2 particle size would lead to faster conversion of Ti3AlC2 to its 2-D Ti3C2 counterpart [16, 17]. For example, it is reported that at least 24 h is needed for etching Al from Ti3AlC2 powders passed through a 325-mesh screen in 49% HF solution at 60°C to prepare 2-D Ti3C2 [18]. Therefore, developing a novel process to synthesize fine-grained Ti3AlC2 powders is necessary. Unsurprisingly, the molten salt method, as a relatively low-temperature technique for nanosized carbide synthesis, has attracted increasing interest in recent years [19,20]. Salt is used as a liquid medium in this method, causing faster reactions at relatively lower temperatures and reaction completion in a shorter time [21]. Until now, Ti3SiC2 and Cr2AlC have been successfully synthesized by the molten salt method [22, 23]. Unfortunately, the particle size of the prepared MAX phases is also larger than a few microns. Therefore, it is urgent to decrease the grain size of the obtained Ti3AlC2 powder or explore a novel process to synthesize submicron or nanosized Ti3AlC2 grains to facilitate the faster conversion of Ti3AlC2 to its 2- D Ti3C2 counterpart. This work aims to report on synthesizing nanosized Ti3AlC2 powder by molten salt method at a relatively low temperature to obtain a faster conversion of Ti3AlC2 to its 2-D Ti3C2 counterpart.
