Characterization of the prepared Ti3AlC2


The typical FE-SEM microstructure of Ti3AlC2 powder obtained from 3Ti/Al/2C starting elemental powders in NaCl‒KCl molten salt at 1000 °C for two h and the corresponding XRD pattern. Pproducts are composed of homogeneous particles with a particle size of ˜100 nm. An energy-dispersive X-ray spectroscopy (EDS) spectrum illustrates that only Ti, Al, and C elements are detected, further suggesting that the Ti3AlC2 compound is synthesized. In addition, the elemental mapping analysis of Ti3AlC2 nanoparticles reveals that the element of Ti, Al, and C are uniformly distributed in the sample obtained. Combined with the XRD results in Fig. 3 curve g, it is confirmed that the homogeneous Ti3AlC2 nanoparticles are prepared by this molten salt method. The representative microstructure of the Ti3AlC2 nanoparticles obtained from 3Ti/Al/2C starting elemental powders in NaCl‒KCl molten salt at 1000 °C for two h is also characterized by TEM. The TEM images of Ti3AlC2 nanocrystallines show that the average size of Ti3AlC2 particles is approximately 100 nm. The Tyndall scattering eff;ect for the suspension of Ti3AlC2 nanoparticles in deionized water by shining a laser beam through the solution. This suggests that the Ti3AlC2 nanoparticle was a colloidal solution with high hydrophilicity and dispersibility.

Furthermore, the typical layer structure of Ti3AlC2 powder is seen in TEM and HRTEM images. The obvious lattice fringes reveal that the Ti3AlC2 is well-crystallized. The layered atomic stacking and the corresponding SAED pattern on the surface of the obtained Ti3AlC2 powder can also be identified in the HRTEM image.
