WebHafnium diboride also suffers from high susceptibility to material degradation with boron transmutation, but its high melting point of 3,380 °C and the large thermal neutron capture cross section of hafnium of 113 barns and low reactivity with refractory metals such as tungsten makes it an attractive control rod material when clad with a refractory metal. WebAs noted above, the rare-earth elements—especially the lanthanides—are quite similar. They occur together in nature, and their complete separations are difficult to achieve. However, there are some striking differences, especially in the physical properties of the pure metallic elements. For example, their melting points differ by nearly a factor of two, …
