Zn-Zr co-doped yttrium-magnesium composite ceramic powder as well as preparation method and application thereof
The invention discloses Zn-Zr co-doped yttrium-magnesium multiphase ceramic powder and a preparation method and application thereof.The Zn-Zr co-doped yttrium-magnesium multiphase ceramic powder comprises yttrium oxide, magnesium oxide, zinc oxide and zirconium oxide, the volume ratio of yttrium oxide to magnesium oxide is 0.9-1.2: 1, and the mass ratio of zinc oxide to zirconium oxide is 1: 1-5; in the Zn-Zr co-doped yttrium-magnesium composite ceramic powder, the total mass fraction of zinc oxide and zirconium oxide is less than 15%. According to the embodiment of the invention, Zn and Zr are doped in the yttrium-magnesium multiphase ceramic powder, Zn replaces Mg, Zr replaces Y, and Zn-Zr is doped, so that the refractive index of a magnesium oxide phase is improved, the refractive index difference between the magnesium oxide phase and an yttrium oxide phase is reduced, and the transmittance of the ceramic prepared from the yttrium-magnesium multiphase ceramic powder is improved; meanwhile, Zn and Zr are doped, so that solid solution toughening is facilitated, the material strength is improved, and the bending strength of the prepared ceramic is improved.
本发明公开了Zn‑Zr共掺钇镁复相陶瓷粉体及其制备方法和应用，其中，Zn‑Zr共掺钇镁复相陶瓷粉体包括氧化钇、氧化镁、氧化锌和氧化锆，其中氧化钇和氧化镁的体积比为0.9‑1.2:1，所述氧化锌和氧化锆的质量比为1:1‑5；所述Zn‑Zr共掺钇镁复相陶瓷粉体中，所述氧化锌和氧化锆的总质量分数小于15％。本发明实施方式在钇镁复相陶瓷粉体中掺杂Zn和Zr，其中，Zn取代Mg，Zr取代Y，Zn‑Zr的掺入有利于提高氧化镁相的折射率，减小氧化镁相与氧化钇相的折射率差异，从而提高由其制备的陶瓷的透过率；同时，掺杂Zn和Zr有利于固溶增韧，提高材料强度，有利于提高由其制备的陶瓷的抗弯强度。
