Tantalum
Revision as of 19:03, 15 June 2005 by 192.168.3.13 (talk)
Tantalum (element Ta, #73 of the periodic table) has a high melting point and is resistant to water, air and acid degradation. It is therefore very useful in many different alloys meant to be subjected to stressful environs, or where something very small has to be very strong. Tantalum is used extensively in small devices as an ingredient in capacitors.
There are no US tantalum mines.
