Colored zirconia transparent ceramic and preparation method thereof
The invention provides colored zirconia transparent ceramic and a preparation method thereof, the ceramic comprises zirconia, yttrium oxide and a coloring agent, the content of the yttrium oxide is between 7 mol% and 12 mol%, and the content of the coloring agent is between 0.1 mol% and 5 mol%. According to the preparation method disclosed by the invention, the high-activity nano powder prepared by a chemical coprecipitation method is used as a raw material, the zirconium oxide transparent ceramic with high refractive index and colors of purple, pink, yellow, red and the like is prepared through two-step sintering, and the prepared colored zirconium oxide transparent ceramic has high refractive index and high light transmittance; the transparent color zirconia ceramic not only can endow the color zirconia ceramic with high-grade texture, but also can widen the application range of the zirconia ceramic in more fields, and the transparent color zirconia ceramic can be used as a high-grade electronic equipment part, a high-end decoration material, a gem material and the like, and can also be used as an optical filter, an aviation navigation and traffic signal lampshade and the like.
本发明提供了一种彩色氧化锆透明陶瓷及其制备方法，所述陶瓷包含氧化锆、氧化钇和着色剂，且所述氧化钇的含量在7mol％至12mol％之间，所述着色剂的含量在0.1mol％至5mol％之间。本发明的制备方法中以化学共沉淀法制备的高活性纳米粉体为原料，通过两步烧结制备具有高折射率的紫色、粉色、黄色、红色等色彩的氧化锆透明陶瓷，制备的彩色氧化锆透明陶瓷具有高的折射率和高的光透过率，此外，透明性不仅能赋予彩色氧化锆陶瓷高级的质感，同时能拓宽氧化锆陶瓷在更多领域的应用，本发明的彩色氧化锆透明陶瓷除了可用作高档电子设备部件、高端装饰以及宝石材料等，还能用作滤光片，航空航海和交通信号灯罩等。
