The invention discloses a method for preparing a 3D gradient color zirconia false tooth ceramic green body, which comprises the following specific steps: surface treatment, soaking with an accelerant, powder distribution according to a proportion, corresponding dyeing, color number marking, multi-layer die casting and sintering molding, and specifically comprises the following steps: firstly, sufficiently soaking zirconia powder with the accelerant for dyeing; the method comprises the following steps of: firstly, adding zirconium oxide powder into coloring agents with different color numbers and chromaticity to obtain zirconium oxide powder with corresponding color numbers and chromaticity, then carrying out multi-layer pressure casting on the zirconium oxide powder with different color numbers and chromaticity for multiple times according to the manufacturing requirement of a gradient color zirconium oxide blank, and enabling the zirconium oxide powder with different colors to be mutually permeated in the pressing process to obtain the gradient color zirconium oxide blank. The closer the distance to the contact surface of the two colors is, the more obvious the penetration is, the color number and the chromaticity are closer before die casting, and during die casting, adjacent zirconia powder permeates mutually, so that the gradual change is more natural, a more perfect visual effect is presented, and a blank body cake material presented by die casting is sintered to form a preliminary zirconia porcelain block.
本发明公开了一种制备3D渐变色氧化锆义齿陶瓷坯体的方法，具体步骤如下，表面处理‑促进剂浸泡‑粉末按比例分配‑对应染色‑色号标记‑多层压铸‑烧结成型，先是将用于染色的促进剂对氧化锆粉末进行充分浸泡，然后再将氧化锆粉末加入到不同色号色度的染色剂中，从而获得对应色号色度的氧化锆粉末，再根据渐变色氧化锆胚体制造的需要，将不同色号色度的氧化锆粉末，进行多次多层的压铸，在压制的过程中，不能颜色的氧化锆粉末相互渗透，距离两种颜色接触面越近则渗透越明显，压铸前色号色度就较为接近，在压铸时，相邻的氧化锆粉末相互渗透，这就使得渐变更加自然，从而呈现更完美的视觉效果，压铸呈现的胚体饼料进行烧结，形成初步的氧化锆瓷块。
