本文报道了一种新的层状三元碳化物Mo2TiAlC2的合成，它是通过在1600℃的氩气流下加热元素混合物4小时合成的。通过粉末x射线衍射图的Rietveld分析计算出其六角形、a型和c型晶格参数分别为2.997埃和18.661埃。高分辨率扫描透射电子显微镜显示，该相是有序的，Ti层夹在两个Mo层之间，呈M(3)AX(2)型三元碳化物结构。(C) 2015材料学报Elsevier Ltd.出版。版权所有。
Herein we report on the synthesis of a new layered ternary carbide, Mo2TiAlC2, that was synthesized by heating an elemental mixture at 1600 degrees C for 4 h under an Ar flow. Its hexagonal, a and c lattice parameters were calculated via Rietveld analysis of powder X-ray diffraction patterns to be, respectively, 2.997 angstrom and 18.661 angstrom. High-resolution scanning transmission electron microscopy showed that this phase is ordered, with Ti layers sandwiched between two Mo layers in a M(3)AX(2) type ternary carbide structure.
