Neodymium-doped zircon-based ceramic solidified body and preparation method thereof
The invention belongs to the field of ceramic solidified bodies, and particularly relates to a neodymium-doped zircon-based ceramic solidified body and a preparation method thereof. The invention provides a neodymium-doped zircon-based ceramic solidified body, the chemical composition of the neodymium-doped zircon-based ceramic solidified body is Zr < 1-x > Nd < x > SiO < 4-x/2 >, x is equal to 0.02-0.1, crystal grains are fine and uniform, the particle size is 0.3-0.9 mu m, and the neodymium-doped zircon-based ceramic solidified body powder does not contain other elements except zircon and neodymium elements. The preparation method of the neodymium-doped zircon-based ceramic solidified body comprises the following steps: mixing ZrO2 powder, SiO2 powder and Nd2O3 powder to obtain mixed powder; carrying out wet grinding on the mixed powder and eutectic salt to obtain a precursor; sequentially drying and sintering the precursor to obtain a sintered product; and washing the sintered product with water to obtain the neodymium-doped zircon-based ceramic solidified body. According to the method, the neodymium-doped zircon-based ceramic solidified body powder with fine and uniform crystal grains and high synthesis rate can be obtained at a relatively low temperature within a short time, and the process is simple to operate.
本发明属于陶瓷固化体领域，具体涉及一种掺钕锆石基陶瓷固化体及其制备方法。本发明提供了一种掺钕锆石基陶瓷固化体，化学组成为Zr1‑xNdxSiO4‑x/2，其中x＝0.02～0.1，晶粒细小均匀，粒径为0.3～0.9μm，本发明的掺钕锆石基陶瓷固化体粉末，除锆石和钕元素，不含有其他元素。本发明的掺钕锆石基陶瓷固化体的制备方法是通过将ZrO2粉体、SiO2粉体和Nd2O3粉体混合，得到混合粉体；将所述混合粉体和共晶盐湿磨，得到前驱体；将所述前驱体依次进行干燥和烧结，得到烧结产物；将所述烧结产物水洗，得到所述掺钕锆石基陶瓷固化体。本发明可以在较低温度下、短时间内获得晶粒细小均匀、高合成率的掺钕锆石基陶瓷固化体粉末，工艺操作简单。
