Abstract Y0.16Zr0.84O1.92 transparent ceramics were successfully fabricated by air pre-sintering combined with HIP post-treatment from the nanopowder synthesized by the co-precipitation method. Fine and low-agglomerated Y0.16Zr0.84O1.92 powder with the average particle size of 14.8 nm was obtained by calcining the precursor at 800 °C for 4 h. The influences of pre-sintering temperature on the microstructure and optical quality of Y0.16Zr0.84O1.92 ceramics were investigated. It is found that the relative density of pre-sintered Y0.16Zr0.84O1.92 ceramics increases from 82.1% to 96.1% and the average grain size increases from 0.6 μm to 6.0 μm with the pre-sintering temperature increasing from 1250 °C to 1500 °C. The Y0.16Zr0.84O1.92 ceramic sample pre-sintered at 1300 °C for 2 h and HIP post-treated at 1800 °C for 3 h without sintering additives exhibits the best transparency. In-line transmittance of Y0.16Zr0.84O1.92 ceramics with the thickness of 1.0 mm reaches 72.4% at 800 nm, which is near to the theoretical transmittance.

摘要 以共沉淀法合成的纳米粉体为原料，通过空气预烧结结合HIP后处理，成功制备了Y0.16Zr0.84O1.92透明陶瓷。通过将前驱体在 800°C 下煅烧 4 小时，获得了平均粒径为 14.8 nm 的精细且低团聚的 Y0.16Zr0.84O1.92 粉末。研究了预烧结温度对Y0.16Zr0.84O1.92陶瓷显微组织和光学质量的影响。结果表明，随着预烧结温度从 1250 ℃提高到 6.0 μm，预烧结 Y0.16Zr0.84O1.92 陶瓷的相对密度从 82.1% 增加到 96.1%，平均晶粒尺寸从 0.6 μm 增加到 6.0 μm。 1500℃。Y0.16Zr0.84O1。92 陶瓷样品在 1300 °C 下预烧结 2 h 和在 1800 °C 下 HIP 后处理 3 h 没有烧结添加剂表现出最好的透明度。厚度为1.0 mm的Y0.16Zr0.84O1.92陶瓷在800 nm处的在线透射率达到72.4%，接近理论透射率。
