2018-11-11 · Abstract. Zirconium is an ideal material for nuclear reactors due to its low absorption cross-section for thermal neutrons, whereas the typically contained hafnium with strong neutron-absorption is very harmful for zirconium.
2018-11-16 · Hafnium is a chemical element with syol Hf and atomic nuer 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically reseles zirconium and is found in many zirconium minerals. Its existence was predicted by Dmitri Mendeleev in 1869, though it was not identified until 1923, by Coster and Hevesy, making it the last
