Formula and process of dental transparent porcelain containing rare earth elements
The invention relates to a formula and a process of dental transparent porcelain containing rare earth elements. The adopted technical scheme is as follows: the chromaticity of the ceramic powder is controlled by introducing the content of rare earth elements in the ceramic powder, the transparency is improved by sintering in a vacuum furnace, and all the components are weighed, uniformly mixed and then sintered at high temperature in the vacuum furnace for use. The method has the beneficial effects that the rare earth element can meet the color requirement through a large number of experiments, and meanwhile, the transparency can be improved through sintering under the vacuum condition; the rare earth elements are added into the formula, so that different chromaticity of teeth under different light rays can be increased, and the vacuum furnace is adopted for sintering during sintering, so that the transparency can be improved, meanwhile, bubbles can be favorably discharged, and the sintered teeth are more compact. Perfect combination of transparency and chromaticity can be achieved only through energy saving of one kind of porcelain powder, the working intensity is reduced, and the working efficiency is improved.
本发明涉及一种牙科用含稀土元素的透明瓷的配方及工艺。采用的技术方案是：通过引入瓷粉里稀土元素的含量来控制瓷粉的色彩度，通过使用真空炉烧结来提高透度，称量各组分混合均匀后在真空炉高温烧结使用。本发明的有益效果：通过大量实验找到稀土元素可以做到能满足颜色的需求，同时在真空的条件下烧结又可以使透度进行提高；通过在配方中添加稀土元素可以增加牙齿在不同光线下的不同色彩度，在烧结时采用真空炉烧结可以在提高透度的同时还有助于气泡的排出，使得烧结的更加致密。只需要上一种瓷粉节能达到透度和色彩度两者的完美结合，减少工作强度，提高工作效率。
