PROBLEM TO BE SOLVED : To obtain a transparent rare earth garnet ceramic at a low cost for a short time as a scintillator material for an X-ray detector.
SOLUTION : The rare earth garnet ceramic that can be used as a scintillator element (24) is formed with accurate control of the rare-earth/alumina ratio, thereby the transparency within the elements is increased to a desired ratio. The ceramic is formed by milling together suitable sub-micrometer rare earth oxide powders and sub-micrometer alumina powders in a desired ratio. The milled powders are then made into a compact and sintered to form the rare earth garnet ceramic having the desired transparency. |
