There are lots of rusts, which are oxidation products of metals. The common one is that of iron, ferric oxide Fe2O3. As a mineral it is called hematite. As Fe2O3 is formed, it is brittle and it breaks off, exposing deeper atoms of Fe to further oxidation. Contrast that behavior with Al. It oxidizes on its surface to Al2O3, but that "rust", called aluminum oxide or alumina, remains and protects the deeper Al atoms from further oxidation.
and the formula is fe2o3.xh2o
