What is Tantalum? Tantalum (Ta) is very hard, malleable, has high corrosion resistance, high electrical & heat conductor, and can be welded. The melting temperature of Tantalum is very high 5463°F or 3017°C. The microstructure of tantalum is body-centered cubic (BCC). Due to its high hardness, grinding tantalum is not practical.
Recrystallization, tensile, and creep-rupture behavior of high-purity tantalum and two interstitial-containing tantalum alloys have been determined. After a 75 per cent cold reduction, tantalum was completely recrystallized on annealing 1 hr at 1200 C; this temperature was increased slightly by adding 560 ppm oxygen.
