摘要: 采用自蔓延高溫合成(SHS)技術制備鈣鈦礦(CaTiO₃)固化體,通過多種現代分析技術研究了鈣鈦礦固化體的微觀組織、浸出率以及其對高放廢物的最大包容量。結果表明,固化體樣品密度高,孔隙率小,浸出率低,對srO的包容量可達到35%(質量分數).自蔓延高溫合成的鈣鈦礦人造巖石是固化鍶核素的理想固化體.

Abstract: Perovskite synroc samples were synthesized by Self-propagating High-temperature Synthesis (SHS), and their properties, including leach rate, density, microhardness and the largest High Level radioactive Waste (HLW) content held in the samples, were tested by X-ray diffraction and scanning electron microscopy. The results indieate that the Sr²⁺-CaTiO₃ compound with high density are formed and the largest SrO content in the compound can reach 35% in mass fraction. It can be concluded that the perovskite synroc is a perfect material to immobilize HLW.
