摘    要:采用自蔓延高温合成(SHS)技术制备钙钛矿(CaTiO3)固化体,通过多种现代分析技术研究了钙钛矿固化体的微观组织、浸出率以及其对高放废物的最大包容量.结果表明,固化体样品密度高,孔隙率小,浸出率低,对SrO的包容量可达到35%(质量分数).自蔓延高温合成的钙钛矿人造岩石是固化锶核素的理想固化体.

关 键 词:钙钛矿  高放废物  固化  自蔓延高温合成(SHS)  自蔓延  高温合成  钙钛矿  人造岩石  固化体  Radioactive  Level  High  Immobilization  Perovskite  核素  质量分数  孔隙率  密度  样品  结果  容量  最大包  高放废物  浸出率

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 indicat 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.
Keywords:perovskite  high level radioactive waste  immobilization  self-propagating high-temperatures synthesis
