WebTantalum has one of the highest melting and boiling points of all the chemical elements [3017 °C (5462 °F) and 5458 °C (9856 °F), respectively]. Its density (16.7 g/cm3), is nearly half again as high as lead’s (11.3 g/cm3). Its thermal conductivity [35 W/(M･K)] is quite low, only 20%-25% of molybdenum’s or tungsten’s, and less than half of iron’s. WebTantalum is immune to attack by many acids and salt solutions. It is, however, subject to hydrogen embrittlement in alkaline solutions. It is used to fabricate heat exchangers, reaction vessels, bayonet heaters, thermo wells, surgical implants and radiation shielding.
