The metal can be isolated from tantalum, and prepared in several ways. It is a shiny, white, soft, and ductile metal, and takes on a bluish cast when exposed to air at room temperatures for a long time. The metal starts to oxidize in air at 200°C, and when processed at even moderate temperatures must be placed in a protective atmosphere.

The feedstock was prepared by mechanically mixing iron ASC 100.29 powder with designated carbon powder for 30 minutes. Powder mass was compacted at 30°C and 150°C by applying simultaneous downward and upward load of 130 kN. The defect-free green compacts were sintered at argon gas fired sintering furnace at different sintering schedule.
