MATERIAL
OVERVIEW
Characteristics:
Lustrous metal. Reacts slowly in water; soluble in
dilute acid; insoluble in water. Exhibits a high
degree of magnetism, especially at lower temperatures.
Salts are colorless. Gadolinium also has the highest
neutron absorption cross-section of any known element.
Gd also has superconductive properties. Combustible,
burns in air to form the oxide.
