Method for preparing photocuring-formed high-density ceramic
The invention relates to the technical field of ceramic preparation, in particular to a method for preparing photocuring-formed high-density ceramic. According to the method, by optimizing the components and matching of slurry, the slurry is suitable for 3D printing preparation of a high-density ceramic special-shaped piece green body which is complex in structure, and no corresponding mold needs to be especially manufactured. Moreover, when the solid content of the slurry is lower than 40 vol%, the slurry can still be used for manufacturing the high-density ceramic green body, and the relative density of high-density ceramic which is manufactured ultimately can reach up to 99%. The green body is dried in a liquid state drying mode, and thus the method is suitable for manufacturing the high-density ceramic green body which is complex and precise in structure. The two-step degreasing method of vacuum/atmosphere protection latex flow and air latex flow is adopted in the method for conducting latex flow, and therefore the defects of deformation, cracking, blistering and the like of the green body can be reduced. The relative density of the high-density ceramic which is prepared through the method is above 90%, the Vickers hardness is above 12 GPa, and the content of residual carbon is smaller than 0.5 wt%.
