The invention relates to the technical field of ceramic materials, and concretely relates to a denture material and a preparation method thereof. The preparation method of the denture material comprises the following steps: carrying out concentration treatment on an yttria-stabilized zirconia suspension containing a dispersing agent, then carrying out molding treatment in a mold, drying to obtain a zirconia green body, and then carrying out glue discharging and sintering. By means of the wet molding method, the superfine nanometer particle size of the raw material powder can be reserved, a denture porcelain block obtained through sintering is uniform in internal structure, the grain size is smaller than 100 nm, the breaking strength is high, the toughness is good, and the yield and the mechanical property of the denture material are effectively improved.
本发明涉及陶瓷材料技术领域，具体而言，涉及一种义齿材料及其制备方法。本发明的义齿材料的制备方法，包括以下步骤：将含有分散剂的氧化钇稳定氧化锆悬浊液进行浓缩处理，再于模具中进行成型处理，干燥后得到氧化锆生坯，再进行排胶和烧结。本发明通过湿法成型的方法，可以保留原料粉体的超细纳米粒径，并使得烧结得到的义齿瓷块内部结构均匀，晶粒尺寸小于100纳米，断裂强度高并且韧性好，有效提高义齿材料的良品率和力学性能。
