采用固相反应和真空烧结的方法制备了Tb3Al5O12透明陶瓷。研究了样品的光学质量和微观结构。在1650℃下烧结的样品在400 nm至1600 nm范围内具有较好的光学透明度。在632.8 nm处测得准无孔Tb3Al5O12透明陶瓷的费尔德常数为-172.72 rad T-1 m(-1)，与Tb3Al5O12单晶的对应物接近。还测量了样品的热导率。据我们所知，这是首次报道具有较好光学质量和磁光性能的Tb3Al5O12透明陶瓷。 (C) 2011 Elsevier B.V. 保留所有权利。
Tb3Al5O12 transparent ceramics have been prepared by solid state reaction and vacuum sintering. The optical quality and the microstructure of the samples were investigated. The sample sintered at 1650 degrees C possessed relatively good optical transparency from 400 nm to 1600 nm. The Verdet constant measured at 632.8 nm of the quasi-pore-free Tb3Al5O12 transparent ceramic was -172.72 rad T-1 m(-1), which was close to the counterpart of Tb3Al5O12 single crystal. The thermal conductivity of the sample was also measured. To the best of our knowledge, this is the first time that Tb3Al5O12 transparent ceramic with relatively good optical quality and magneto-optical property has been reported. (C) 2011 Elsevier B.V.
