Samarium based high surface area perovskite type oxides SmFe1-xAlxO3 (X=0.00, 0.50, 0.95). Part I, synthesis and characterization of materials
High specific surface area (ssa) perovskite type solids based on samarium (SmFe1-xAlxO3, x = 0.00, 0.50, 0.95) were prepared using hexadecyltrimethyl-ammonium bromide C(16)TAB as a precursor and gelating agent. The structure of perovskite is fully developed at 600 degreesC for the SmFeO3 solid but not for the other materials. The ssa of the solids varies (33.5 m(2)g(-1) - 1 m(2)g(-1)) depending on composition and calcination temperature.
