tantalum is a rare hard blue-gray lustrous transition metal that is highly corrosion-resistant. it is part of the refractory metals group which are widely used as minor components in alloys. the chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum.

marketplace tantalum materials are tantalum metal tantalum ore and tantalum powder. in 2006 neither niobium nor tantalum ore was mined domestically. the last signiﬁ cant mining of niobium and tantalum ore in the united states was during the korean war when increased military demand resulted in niobium and tantalum ore shortages. consumption
niobium formerly known as columbium is a chemical element with the symbol nb (formerly cb) and atomic number 41. niobium is a light grey crystalline and ductile transition metal.pure niobium has a hardness similar to that of pure titanium [contradictory] and it has similar ductility to iron.niobium oxidizes in the earth's atmosphere very slowly hence its application in jewelry as a
