Niobium and tantalum are considered chemically similar as they fall within the same vertical group as vanadium in the periodic table. Similar to tantalum, niobium alloys have found wide use in joint arthroplasty, especially for high stress applications as composites of niobium and tantalum are both highly biocompatible. No long-term …
The synthesis of tantalum and niobium fluoride compounds is related to the fluorination of metals or oxides. The fluorination of both metals and oxides of niobium and tantalum can take place even at low temperatures; whereas, fluorination using ammonium fluoride and ammonium hydrofluoride can be performed only at higher temperatures.
