COLTAN - Tantalite Ore Ta205

Description

Chemical Properties
a) Tantalum: *0.*4 % Ta *6.*1 % Ta2O5

b) Iron: *0.*7 % Fe *3.*8 % FeO

c) Oxygen: *8.*9 % O

Typical Applications
The principal ore of niobium and tantalum, used mostly as an additive in steel making and in superalloys; used in metallurgy for heat-resistant alloys, rust-proofing (stainless steel) and electromagnetic superconductors. Brazil and Canada are leading producers. Used in cell phones and computer chips.

Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal.

Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.
