TRANSPARENT CERAMICS, MANUFACTURING METHOD THEREOF, AND MAGNETO-OPTICAL DEVICE
A transparent ceramic material is manufactured by molding a source powder into a compact, the source powder comprising a rare earth oxide consisting of at least 40 mol% of terbium oxide and the balance of another rare earth oxide, and a sintering aid, sintering the compact at a temperature T (1,300°C ≤ T ≤ 1,650°C) by heating from room temperature to T1 (1200°C ≤ T1 ≤ T) at a rate of at least 100°C/h, and optionally heating from T1 at a rate of 1-95°C/h, and HIP treating the sintered compact at 1,300-1,650°C. The ceramic material has improved diffuse transmittance in the visible region and functions as a magneto-optical part in a broad visible to NIR region.
