TRANSPARENT SPINEL SINTERED BODY, OPTICAL MEMBER AND METHOD FOR PRODUCING TRANSPARENT SPINEL SINTERED BODY
Provided is a transparent spinel sintered body which is formed from an Mg-Al spinel powder having an Al/Mg ratio of from 1.97 to 2.03 or a mixed powder of an Mg oxide and an Al oxide, and wherein the total content of metal impurities excluding Al and Mg is less than 100 ppm. A sample of this transparent spinel sintered body having a thickness of 3 mm has a total light transmittance of 80% or more in the thickness direction for the wavelength range of from 190 nm to 400 nm; and this transparent spinel sintered body is usable as a medium that transmits light from an ultraviolet light emitting element.
