METHOD FOR MANUFACTURING GADOLINIUM OXYSULFIDE CERAMIC SCINTILLATOR
PROBLEM TO BE SOLVED: To provide a method for manufacturing GOS (having a general formula of GdOS [gadolinium oxysulfide]) ceramic scintillator at a low-cost by two stage sintering including a primary sintering by uniaxial compression and a secondary sintering by hot isotropic compression.SOLUTION: Provided is a method for manufacturing GOS ceramic scintillator, in which the GOS ceramic scintillator sintering step is divided into two stages, that is, in accordance with a sintering process by uniaxial compression, a GOS powder, and a sintering aid added thereto, are uniformly mixed (1001), and the powder is charged into a sintering mold to produce a primary sintered body having closed spaces (1002), and the sintered body is annealed (1003), and in accordance with a sintering process by hot isotropic compression with inert gas, a high density secondary sintered body is produced (1004), and the secondary sintered body is treated, to then obtain the GOS ceramic scintillator (1005).SELECTED DRAWING: Figure 1
【課題】一軸加圧による一次焼結と熱間等方圧加圧による二次焼結とを含む二階段焼結でＧＯＳ（一般式Ｇｄ2Ｏ2Ｓ〔ガドリウムオキシサルアイド〕を有する）セラミックシンチレータを低コストに製造する方法の提供。【解決手段】ＧＯＳセラミックシンチレータの焼結過程を二段階に分けて行い、即ち一軸加圧による焼結方法でＧＯＳ粉体を焼結助剤を添加し均一に混合し、（１００１）、前記粉末と焼結鋳型内に入れ、閉鎖空間を有する一次焼結体を製造し１００２、前記焼結体を焼鈍し１００３、不活性ガスでの熱間等方圧加圧による焼結方法で高密度の二次焼結体を製造し１００４、二次焼結体を処理した後にＧＯＳセラミックシンチレータを取得する１００５製造方法。【選択図】図１
