In this work, transparent sub-mircon Gd₂Zr₂O₇ (GZO) ceramic was successfully sintered for the first time by spark plasma sintering (SPS) using nanocrystalline powders synthesized via a solvothermal assisted co-precipitation route. With the aids of fast heating and cooling rate and high pressure, the GZO transparent sample with an average grain size of about 205 nm was obtained at 1400 °C for 5 min. The maximum transmittance of about 70% was achieved at a wavelength of 2000 nm.

纳米晶粉末火花等离子体烧结制备透明亚微晶Gd ₂ Zr ₂ O ₇陶瓷

在这项工作中，使用通过溶剂热辅助共沉淀途径合成的纳米晶体粉末，通过火花等离子体烧结（SPS）成功地首次成功烧结了透明的亚微晶Gd ₂ Zr ₂ O ₇（GZO）陶瓷。借助快速的加热和冷却速度以及高压，在1400°C下5分钟获得了平均晶粒尺寸约为205 nm的GZO透明样品。在2000 nm的波长下可获得约70％的最大透射率。
