Universal method for rapidly preparing MAX-phase or MAB-phase material

The invention belongs to the technical field of inorganic materials, and particularly discloses a universal method for rapidly preparing an MAX phase or MAB phase material, which comprises the following steps: preparing a precursor, performing pulse high-temperature solid-phase reaction sintering on the precursor material, and removing impurities to obtain the high-purity MAX phase or MAB phase material. According to the method, the defects that a traditional continuous heating method is low in speed, low in efficiency and the like are overcome, a simple pulse high-temperature method is developed to achieve rapid preparation of the MAX phase or MAB phase material within 1 min, the total heat treatment duration is shortened by 3-5 orders of magnitude compared with a traditional several-hour long heating process, time can be effectively saved, and energy consumption and cost can be effectively reduced. 本发明属于无机材料技术领域，具体公开了一种快速制备MAX相或MAB相材料的通用方法，包括如下步骤：前驱体制备、前驱体材料的脉冲高温固相反应烧结、清除杂质，得到高纯度MAX相或MAB相材料。本发明突破了传统连续加热法速度慢
