  • Hafnium Wikipedia

    However, because of hafnium's neutronabsorbing properties, hafnium impurities in zirconium would cause it to be far less useful for nuclearreactor applications. Thus, a nearly complete separation of zirconium and hafnium is necessary for their use in nuclear power. The production of hafniumfree zirconium is the main source for hafnium.
