Abstract
Provided is a method of manufacturing a transparent sesquioxide sintered body by which a transparent MOtype sesquioxide sintered body can be manufactured. A powder including particles of an oxide of at least one rare earth element selected from Y, Sc or lanthanide elements and Zr oxide particles is prepared as a raw material powder, wherein in the particle size distribution of the rare earth element oxide particles, or in the particle size distribution of secondary particles in the case where the rare earth element oxide particles are agglomerated to form the secondary particles, the particle diameter Dvalue at which the cumulative particle amount from the minimum particle size side is 2.5% based on the total particle amount is in the range from 180 nm to 2000 nm, inclusive. The raw material powder is press molded into a predetermined shape, followed by sintering.
