Hafnium has good corrosion resistance and high strength. It resists corrosion due to formation of a tough, impenetrable oxide film on its surface. Hafnium is unaffected by alkalis and acids, except hydrofluoric acid. Hafnium is difficult to separate form zirconium, because the two elements have atoms that are the same size. Hafnium and its alloys are used for control rods in nuclear reactors and nuclear submarines because hafnium is excellent at absorbing neutrons and it has a very high melting point and is corrosion resistant. It is used in high-temperature alloys and ceramics, since some of its compounds are very refractory: they will not melt except under the most extreme temperatures.
