Method for preparing Ti2AlC ceramic material at low temperature
A method for preparing Ti2AlC ceramic material at the low temperature comprises steps as follows: Ti powder, Al powder and TiC powder are selected as raw materials, firstly, the raw materials are subjected to ball milling and mixing in a certain mole ratio and then are pressed to form blocks, the pre-pressed blocks are put in an air furnace to be subjected to a thermal explosion reaction, the reacted block samples are taken out and cooled to the room temperature, oxidation layers on surfaces of the samples are rubbed off, the block samples without the oxidation layers are broken and subjected to ball milling, powder is obtained, and the high-purity Ti2AlC ceramic material can be obtained after acid treatment, washing and drying. The prepared Ti2AlC ceramic material has stable technological parameters, the method is suitable for large-scale production of the Ti2AlC ceramic material, and the method has the characteristics that the process is simple, the synthesis temperature is low, the preparation time is short and the purity is high.
