Preparation process of zirconia ceramic prosthesis
The invention relates to a ceramic structure processing technology, in particular to a preparation technology of a zirconia ceramic prosthesis. The invention aims to provide the preparation process capable of producing the zirconia ceramic prosthesis with excellent performance. The preparation process of the zirconia ceramic prosthesis comprises the following steps: S10, mixing and grinding zirconia powder, a stabilizer and a sintering aid to obtain slurry; on the basis of the weight of the zirconium oxide powder, the adding amount of the stabilizer is 0.01-0.15 wt%, and the adding amount of the sintering aid is 0.2-0.5 wt%; s20, a solvent is added into the slurry, uniform mixing and spray drying are performed, and particles are obtained; s30, the particles are placed in a mold and subjected to cold press molding under the pressure of 200-400 MPa, and a green body is obtained; s35, drying the green body; s40, the green body is subjected to heat preservation at the temperature of 750-1200 DEG C, pre-sintering is completed, and a biscuit is obtained; and S50, sintering the biscuit in a sintering furnace in an air atmosphere or a vacuum atmosphere at 1300-1500 DEG C for 1-5 hours to obtain a product.
本发明氧化锆陶瓷假体的制备工艺涉及一种陶瓷结构加工工艺。其目的是为了提供一种能够产出性能优异的氧化锆陶瓷假体的制备工艺。本发明氧化锆陶瓷假体的制备工艺包括以下步骤：S10，将氧化锆粉、稳定剂和烧结助剂混合研磨，得到浆料；以氧化锆粉的重量为基准，稳定剂的加入量为0.01～0.15wt％，烧结助剂的加入量为0.2～0.5wt％；S20，向浆料中加入溶剂，混匀，喷雾干燥，得到微粒；S30，将微粒置于模具中，在200～400MPa下冷压成型，得到生坯；S35，将生坯烘干；S40，将生坯在750～1200℃保温，完成预烧，得到素坯；S50，将素坯空气气氛或真空气氛的烧结炉中，在1300～1500℃烧结1～5小时，得到产品。
