Abstract
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 T(1200° C.≤T≤T) at a rate of at least 100° C./h, and optionally heating from Tat 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.
