Novel Tb₃Sc₂Al₃O₁₂ (TSAG) magneto-optical transparent ceramic was fabricated by vacuum sintering. The phase composition, microstructure, optical quality, thermal properties, and magneto-optical properties of TSAG ceramic were measured. It is shown that the increase in holding time has an effect on the grain size of TSAG ceramic. It is noted that TSAG35 ceramic presents the highest transmittance, corresponding to 81.5 % at the wavelength of 1064 nm. The thermal properties of TSAG ceramic are close to or superior to that of the reported TSAG and TGG crystals. The Verdet constant of TSAG ceramic is comparable to that of reported TSAG crystal, and 1.2 times that of TGG crystal. The results indicate that the novel TSAG ceramic is comparable to TSAG crystal in terms of magneto-optical properties and superior to TGG crystal, making it a candidate material for magneto-optical materials to be used in high-power lasers.

新型 Tb ₃ Sc ₂ Al ₃ O ₁₂(TSAG) 磁光透明陶瓷是通过真空烧结制造的。测量了TSAG陶瓷的相组成、微观结构、光学质量、热性能和磁光性能。结果表明，保温时间的增加对TSAG陶瓷的晶粒尺寸有影响。值得注意的是，TSAG35 陶瓷的透光率最高，在 1064 nm 波长处对应于 81.5%。TSAG 陶瓷的热性能接近或优于报道的 TSAG 和 TGG 晶体。TSAG 陶瓷的 Verdet 常数与报道的 TSAG 晶体相当，是 TGG 晶体的 1.2 倍。结果表明，新型TSAG陶瓷在磁光性能方面与TSAG晶体相当，优于TGG晶体，
