Method of forming yttria gadolinia ceramic scintillator from ammonium dispersed oxalate precipitates
A simplified method of forming polycrystalline translucent-to-transparent yttria-gadolinia scintillators comprises coprecipitating oxalates of the yttria-gadolinia composition, drying the oxalates at about 75 DEG C to 125 DEG C, forming an aqueous suspension of the dried oxalates, and agitating the...

| description | A simplified method of forming polycrystalline translucent-to-transparent yttria-gadolinia scintillators comprises coprecipitating oxalates of the yttria-gadolinia composition, drying the oxalates at about 75 DEG C to 125 DEG C, forming an aqueous suspension of the dried oxalates, and agitating the suspension while admixing an effective amount of an ammonium hydroxide solution to disperse agglomerations of the oxalate coprecipitates. The dispersed oxalates are calcined to substantially fully oxidize the oxalates and form an oxide powder of the yttria-gadolinia composition. The oxide powder is cold pressed to form a compact, and the compact is sintered in a reducing atmosphere or vacuum to form the polycrystalline translucent-to-transparent yttria-gadolinia scintillator. |
