Low-temperature sintered zirconia and application thereof in false tooth preparation
The invention discloses low-temperature sintered zirconia and application thereof in false tooth preparation, and relates to the field of false tooth material preparation, the low-temperature sintered zirconia is prepared from the following raw materials by weight: 84-90% of zirconia powder, 3-8% of rare earth oxide, 2-5% of calcium carbonate, 0.5-1.5% of polyvinyl alcohol, and 0.5-1.5% of silicon dioxide. The preparation method comprises the following steps: uniformly mixing zirconium oxide powder and rare earth oxide, adding a set amount of calcium carbonate, polyvinyl alcohol and silicon dioxide, continuously mixing, carrying out ball-milling treatment on the mixed powder in an air or oxygen atmosphere for 2-4 hours, and carrying out ball-milling treatment on the mixed powder in the air or oxygen atmosphere for 2-4 hours, and carrying out low-temperature sintering on the ball-milled powder to obtain the formed low-temperature sintered zirconium oxide, so that the aesthetic degree and the comfort degree of the false tooth can be improved.
本发明公开了一种低温烧结氧化锆及其在义齿制备中的应用，涉及义齿材料制备领域，该低温烧结氧化锆由以下原料按照重量比例制备而成：氧化锆粉体84‑90％，稀土氧化物3‑8％，碳酸钙2‑5％，聚乙烯醇0.5‑1.5％，二氧化硅0.5‑1.5％。制备时将氧化锆粉体和稀土氧化物混合均匀，并加入设定量的碳酸钙、聚乙烯醇、二氧化硅继续混合，其中添加剂为氧化镧、氧化钆、氧化钇组成的稀土氧化物，将混合后的粉体在空气或氧气气氛下进行球磨处理，球磨时间为2‑4小时，将球磨后的粉体进行低温烧结，得到成型后的低温烧结氧化锆，能够提高义齿的美观度和舒适度。
