| Abstract: | Ln2O3-CaO systems, where Ln=La, Sm, have been prepared by impregnation of calcia with aqueous solutions of Ln nitrates or by mixing both oxides. Decomposition at 1073 K leads to a slight decrease in the specific surface area when starting from Ln2O3, but to a sharp decrease when starting from the nitrates. |
