Separation of Zr and Hf via fractional crystallization of K2Zr(Hf)F6 : a theoretical and experimental study / D.J. Branken
Due to the low absorption cross section for thermal neutrons of zirconium (Zr) in contrast to hafnium (Hf), Zr-metal must essentially be Hf free (<100 ppm Hf) to be suitable for use in nuclear reactors. However, Zr and Hf always occur together in nature, and due to similar chemical and physical p...
