Recently, research on MAX phase materials has been actively conducted. M of MAX phase is made of early transition metal element, A is A-group (IIIA or IVA) element, and X is Carbon or Nitrogen. It has the chemical formula of MnAXn-1, and is called the 211, 312, and 413 groups according to the indices(n=1,2,3). MXene material is characterized by having a layered structure of 2D structure like graphene by etching the element corresponding to A-gruop in the MAX phase. So far, MXene materials have been reported to be applied in various fields. In particular, research is being actively conducted as anode material for Li secondary batteries, electromagnetic wave shielding material, and hydrogen storage alloy material. In the pulse energization active sintering method, the surface of the powder particles is cleaned and activated more easily than the conventional electrical sintering process and material transfers at both the macro and micro level, so that a high-quality sintered body can be obtained at low temperature and fast time. In this study, the MAX phase was synthesized in a short time by using a pulse current active sintering apparatus, and the MXene material was prepared from the synthesized MAX phase and the structure was analyzed.
