Method for preparing fine-grain terbium aluminum garnet-based magneto-optical ceramic
The invention relates to a method for preparing fine-grain terbium aluminum garnet-based magneto-optical ceramic, which comprises the following steps: carrying out ball milling treatment on terbium aluminum garnet-based nano powder, a sintering aid and a solvent to obtain slurry, drying, sieving and preparing a ceramic biscuit, the sintering aid is selected from at least one of tetraethoxysilane, magnesium oxide, zirconium oxide, titanium oxide, germanium oxide and the like, and the total addition amount of the sintering aid is 0.001-1wt% of the terbium aluminum garnet-based nano powder; and carrying out pre-sintering and hot isostatic pressing sintering on the obtained ceramic biscuit to obtain the fine-grain transparent terbium aluminum garnet-based magneto-optical ceramic.
本发明涉及一种制备细晶粒铽铝石榴石基磁光陶瓷的方法，包括：将铽铝石榴石基纳米粉体、烧结助剂和溶剂进行球磨处理得到浆料后，再进行干燥、过筛和制成陶瓷素坯，所述烧结助剂选自正硅酸乙酯、氧化镁、氧化锆、氧化钛、氧化锗等中的至少一种，所述烧结助剂的总添加为铽铝石榴石基纳米粉体的0.001～1wt%；将所得陶瓷素坯进行预烧结和热等静压烧结，得到细晶粒透明铽铝石榴石基磁光陶瓷。
