Notes:
La and Sr have recognized as elements of high level radioactive wastes immobilized bysolid solution with CaTiO3. For forming solid solution with CaTiO3, the solution combustionsynthesis (SCS) process was applied and the powder characteristics and sinterability wereinvestigated. The proper selection of the type and the composition of fuels are important to get thecrystalline of CaTiO3. When glycine or the mixtures of urea+citric acid with stoichiometriccomposition was used, the solid solutions of Ca(La, Sr)TiO3 were entirely produced. Thecombustion synthesized powder seemed to have a good sinterability with the linear shrinkage ofmore than 23% up to 1400oC, while that of the solid state reacted powder was less than 19% at thesame conditions
