Hafnium is a shiny, silvery, ductile metal that is corrosion-resistant and chemically similar to zirconium (due to its having the same number of valence electrons, being in the same group, but also to relativistic effects; the expected expansion of atomic radii from period 5 to 6 is almost exactly cancelled out by the lanthanide contraction).
The principal ore of aluminum is bauxite, a complex mixture of a number of aluminum hydroxides and hydrous aluminum oxides. The most common aluminum-bearing minerals in bauxite are gibbsite (AlOH3), boehmite (AlO(OH)), and diaspore (AlO(OH)).
The predominate minerals are rutile, which is about 95 percent titanium dioxide (TiO 2), and ilmenite (FeTiO 3), which contains 50 to 65 percent TiO 2.A third mineral, leucoxene, is an alteration of ilmenite from which a portion of the iron has been naturally leached.
