Experimental of Titanium Aluminum Carbide

Ti, Al (supplied by Beijing Xing Rong Yuan Technology Co., LTD., 325 mesh, purity >99.8%), and acetylene black powders (Tianjin day first Century Chemical Industry Co. Ltd, the average particle size of 30-50 nm, purity >99.9%) were used as starting materials without ball milling in this study. A eutectic NaCl‒KCl (supplied by Tianjin Kemiou Chemical Reagent Co., Ltd. analytical grade≥99.5%) molten salt was used as reaction medium, which was dried under vacuum at 300 °C for 24 h to remove residual water. Starting materials with a molar ratio of 3Ti/Al/2C were weighed and mechanically mixed at mass ratios of the dried salt to starting materials of 1:1 and 10:1 in an alumina crucible. After that, the crucible was placed in the bottom of a vertical tubular stainless steel vessel with an inside diameter of 110 mm and a height of 600 mm placed inside a vertical tube furnace. Then, the vessel was heated to the target temperature at a rate of 6 °C min-1 and held for different times under a flowing argon atmosphere. After the reaction, the chamber was naturally cooled to room temperature. Then the sample was ultrasonically rinsed with boiling deionized water several times to remove the solidified salt. Finally, the sample was dried at 80 °C for ten h. The X-ray diffraction (XRD, PANalytical X’Pertpro) with Cu target Kα radiation was carried out to identify the phase constituents of the samples. The microstructure and morphology of the sample were characterized by field-emission scanning electron microscopy (FE-SEM, FEI FP 2031/11 inspect F) coupled with energy dispersive X-ray spectrometer (EDX, Oxford) and high-resolution transmission electron microscopy (HRTEM, JEM-2100 F, JEOL, Tokyo, Japan) and selected-area electron diffraction (SAED).
