The Hardworking Element Hafnium | ChemTalk
WEBSince hafnium is very corrosion- and heat-resistant and a good absorber of neutrons, the element has many applications in industries and technologies. Hafnium is useful in nuclear submarines and nuclear reactor control rods, a critical technology to maintain fission reactions, because it absorbs neutrons well.
