Perovskite is a major mineral of Synroc material. It is able to confine both alkaline and alkaline-earth elements contained in radioactive waste. Perovskite exists in several crystallographic forms, making them suitable for the confinement of both actinides and alkaline/ alkaline-earth elements. The main challenge in the field of sequestration of radionuclides in such crystalline structure is to accommodate great amounts of actinides/lanthanides and alkaline elements, in the same time in perovskite lattice. For this both dry and wet processes of synthesis are experimented. This study summarize many investigations on both simple Ca(1-x-y)CexSr y Alz Ti(1-z)O3 perovskite (y = 0.04 to 0.16) co-doped with Ce and complexe perovskite [Ca0.91-xCe0.09Rb0.04Csx[(Zr0.50Ti0.45) Al0.05]O3, x=0.2 to 0.4], synthesized by dry and route processes. Thorough full structural and chemical durability’ characterizations are described for both materials.
