Profile: Stanford Advanced Materials is a supplier of a series of pure metals, alloys, ceramics and minerals such as oxides, chlorides, sulfides, & oxysalts. Tantalum is a shiny, silvery colored metal which is heavy, dense, malleable and ductile when pure. It is found in small quantities in minerals (generally in conjunction with niobium), and is isolated by conversion to the oxide and then the fluoro-complex, K2TaF7, from which the pure metal is obtained by electrolysis. Tantalum is extremely corrosion resistant due to the formation of an oxide film, and is also resistant to acid attack (with the exception of HF). It will react with fused alkali and a variety of non-metals at elevated temperatures. We supply tantalum ingots and a wide variety of tantalum products. Other shapes are also available upon request including tantalum foil / strip, tantalum sheet / plate, tantalum tube / pipe, tantalum capillary, tantalum wire and tantalum bar / rod.
