niobium processing
Four one-millimetre thick samples of niobium metal foil.
During the hydriding process in niobium processing, the impure metal is placed in a furnace that is evacuated and heated to a temperature range of 800–950 °C (1,450–1,750 °F). Once this temperature is reached, hydrogen is introduced and passed over the material for a period of two to four hours to complete the hydriding phase.1
