Abstract

The invention relates to zirconium-doped yttria base transparent ceramic and a preparation method thereof. The structural formula of the ceramic is (Y(1-x-y)RexZry)2O3, wherein Re is a rare earth element selected from Yb, Nd, Tm, Ho, Ce, Er, Pr and Eu, or double-elements of Yb doped with Ho, Ce, Er, Pr and Eu; x is more than or equal to 0.00 and is less than or equal to 0.10, and y is more than orequal to 0.001 and is less than or equal to 0.05. The zirconium-doped yttria base transparent ceramic prepared by the method has higher transparency and compactness.

Description

technical field

[0001] The invention relates to a transparent ceramic, in particular to a zirconium-doped yttrium oxide-based transparent ceramic and a preparation method thereof. Background technique

[0002] Yttrium oxide (Y 2 o 3 ) belongs to the cubic crystal system, has the characteristics of good stability, wide optically transparent area, and high thermal conductivity, and has long been considered as an excellent solid-state laser matrix material. Added Nd in recent years 3+ 、Eu 3+ , Yb 3+ Y such as rare earth elements 2 o 3 Transparent ceramics have become a research hotspot of working materials for solid-state lasers. However, due to its melting point as high as 2430 °C and a phase transition around 2280 °C accompanied by a volume change, single crystal growth is difficult. Preparation of transparent Y by ceramic technology 2 o 3 Ceramics are not only easy to prepare, low in cost, and can produce large-scale products, but also can achieve high-concentratio...
