Embodiment 1
[0023] 1) First, Ti, Al and TiC are used as raw materials, Sn and Si are used as synthetic aids, and raw material powders are used to prepare a mixture, where the molar ratio is Ti:Al:TiC:Sn:Si=1.0:1.2:2.0: 0.05:0.05;
[0024] 2) Next, put the mixed material in a ceramic ball mill tank, add ethanol equal to the quality of the mixed material as a ball milling aid, the grinding medium is alumina balls, the speed of the ball mill is 900 rpm, the quality of the alumina balls and the mixed material The ratio is 3:1; ball mill for 1 hour to obtain a uniform powder and dry it at 40°C;
[0025] 3) Then, place the dried mixture in a corundum crucible in a vacuum sintering furnace, heat it from room temperature to 1350°C at a heating rate of 8°C / min under vacuum, sinter in vacuum without pressure, and keep it for 1h;
[0026] 4) Finally, after the heat preservation is over, cool down to room temperature with the furnace to obtain high-purity Ti 3 AlC 2 Ceramic powder.
