Alumina powder is impregnated with samarium (Sm), gadolinium (Gd) and erbium (Er) metals and is characterized by nitrogen adsorption at 77 K. It is observed that these metals on impregnation do not contribute any extra surface to alumina. The values of surface area and pore volume determined from nitrogen adsorption follows the sequence: Alumina > Sm-alumina > Gd-alumina > Er-alumina, and their behaviour is discussed in term of ionic radii of metal ions. It is also observed that meso and macropores contribute significantly to the total pore volume.

Keywords: Alumina, samarium, gadolinium, erbium.
