Method for preparing Gd2Zr2O7 transparent ceramic through vacuum pressureless sintering
The invention discloses a method for preparing Gd2Zr2O7 transparent ceramic through vacuum pressureless sintering, and particularly relates to a method for preparing the Gd2Zr2O7 transparent ceramic at a relatively low temperature through a vacuum pressureless single-step sintering method by adopting a composite sintering aid. The method comprises the steps: taking Gd2Zr2O7 powder as raw materialpowder, adding a small amount (less than or equal to 2.5 percent) of a mixture of Y2O3, La2O3 and HfO2 as a sintering aid, performing ball-milling and mixing to prepare a biscuit, and performing vacuum pressureless single-step sintering at a relatively low temperature (1650 DEG C-1750 DEG C) to obtain the Gd2Zr2O7 transparent ceramic with good optical transmittance.
本发明公开了一种真空无压烧结制备GdZrO透明陶瓷的方法，特别是指采用复合烧结助剂，通过真空无压单步烧结的方法，在相对较低温度下实现GdZrO透明陶瓷制备的一种方法。本发明是采用GdZrO粉作为原料粉，并添加少量(≤2.5％)的YO、LaO、HfO混合物作为烧结助剂，通过球磨混合后制成素坯，再通过相对较低温度下(1650℃－1750℃)真空无压单步烧结，即可获得具有良好的光学透过率GdZrO透明陶瓷。
