Molten Salt Synthesis of Nanolaminated Sc<sub>2</sub>SnC MAX Phase
Abstract
The MAX phases are a family of ternary layered material with both metal and ceramic properties, and it is also precursor materials for synthesis of two-dimensional MXenes. The theory predicts that there are more than 600 kinds of stable ternary layered MAX phase materials. Now, more than 80 kinds of ternary layered MAX phases that the M-site elements are mainly from early transition metal have been experimental synthesized, but few researches are reported on MAX phases where M is a rare earth element. In this study, Sc, Sn and C powders were used as raw materials to synthesize a novel ternary Sc 2 SnC MAX phase via molten salt method. Phase composition and microstructure of Sc 2 SnC were confirmed by X-ray diffraction, scanning electron microscope and X-ray energy
