Abstract:	High specific surface area (ssa) perovskite type solids based on samarium (SmFe_1-xAl_xO₃, x = 0.00, 0.50, 0.95) were prepared using hexadecyltrimethyl-ammonium bromide C16TAB as a precursor and gelating agent. The structure of perovskite is fully developed at 600oC for the SmFeO3 solid but not for the other materials. The ssa of the solids varies (33.5 m²g^-1 - 1 m²g^-1) depending on composition and calcination temperature.

Keywords:	Perovskites samarium surfactant high surface area
