通过真空预烧结和热等静压（HIP）固溶法制备了新型（Tb1-xLux）2O3磁光透明陶瓷。含Lu样品为Tb2O3和Lu2O3之间的固溶相，有效稳定了烧结过程中Tb2O3的相变。选择 x = 0.5 的 (Tb1-xLux)2O3 陶瓷的典型组分来详细研究致密化行为和微观结构演变。厚度为3 mm的抛光(Tb0.5Lu0.5)2O3陶瓷在1.0×10−3Pa、1700 ℃真空预烧并结合1600 ℃ HIP后处理显示出良好的磁光性能。在633 nm处测得的费尔德常数为-224.33 rad·T−1m−1，比Tb3Al5O12(TAG)高30%。然而，633 nm 处的直线透过率为 73.6%，低于 TAG。 (Tb1-xLux)2O3陶瓷在进一步提高光学质量后将成为法拉第器件很有前景的材料。
Novel (Tb1-xLux)2O3magneto-optical transparent ceramics were prepared through a solid-solution method via vacuum pre-sintering followed by hot isostatic pressing (HIP). The Lu-containing samples were solid-solution phases between Tb2O3and Lu2O3, which effectively stabilized the phase transition of Tb2O3during the sintering process. A typical component of (Tb1-xLux)2O3ceramic with x = 0.5 was selected to study the densification behavior and microstructure evolution in detail. The polished (Tb0.5Lu0.5)2O3ceramics with a thickness of 3 mm vacuum pre-sintered at 1700 °C under 1.0 × 10−3Pa combined with HIP post-treatment at 1600 °C showed good magneto-optical property. The Verdet constant measured at 633 nm was -224.33 rad·T−1m−1, 30% higher than that of Tb3Al5O12(TAG). However, the in-line transmittance was 73.6% at 633 nm, lower than that of TAG. The (Tb1-xLux)2O3ceramics will be a promising material for Faraday devices after further improving the optical quality.
