Fine-grained Ce,Y:SrHfO3 Scintillation Ceramics Fabricated by Hot Isostatic Pressing

Ce:SrHfO 3 ceramics possess a strong stopping power to high-energy rays due to their high density and high effective atomic number.However, it is difficult to obtain transparent Ce:SrHfO 3 ceramics via traditional sintering method because of its orthogonal structure.In this work, Ce,Y:SrHfO 3 ceramics were prepared by long-time vacuum sintering and short-time vacuum pre-sintering combined with hot isostatic pressing (HIP).The Ce,Y:SrHfO 3 powders with a pure phase and a mean particle size of 152 nm were prepared by calcining at 1200 ℃
