采用高压火花等离子烧结（HP-SPS）法制备了高红外透明方形ZrO2 （3mol %钇稳定）。所得致密样品的晶粒尺寸约为80 nm。在3 ~ 5 μm波长范围内，1.5 mm厚样品的在线透射率为63% ~ 67%，为理论值的81% ~ 87%。同时，方形ZrO2的截止波长优于其他高强度透明陶瓷。该研究强调了HP-SPS获得透明方形ZrO2的效率和简单性，以及该陶瓷应用于耐用红外窗口的巨大潜力。
Highly infrared transparent tetragonal ZrO2 (3 mol% yttria-stabilized) was prepared by means of high-pressure spark plasma sintering (HP-SPS). The crystallite size of the resulting dense sample was about 80 nm. In-line transmittance for the 1.5 mm thick sample ranged between 63% and 67% in the wavelength of 3–5 μm, representing 81%–87% of the theoretic value. Meanwhile, the cutoff wavelength of tetragonal ZrO2 was superior to the values of other high-strength transparent ceramics. This study highlighted the efficiency and simplicity of HP-SPS for obtaining transparent tetragonal ZrO2 and the great potential of this ceramic applied for durable infrared windows.
