タイトルまたは説明

*Tantalite Ore for sale at excellent terms



*Origin:Republic of Congo/Zambia/DRC



*Port of Loading:Pointe Noire,Republic of Congo / Durban,South Africa



*Properties: Tantalum is a heavy, hard gray metal.



*Pure tantalum is ductile and may be drawn into very fine wire.



*Tantalum is practically immune to chemical attack at temperatures lower than 150 °C.



*It is only attacked by hydrofluoric acid, acidic solutions of the fluoride ion, and free sulfur trioxide. Alkalis attack tantalum very slowly.



*At higher temperatures, tantalum is more reactive.



*The melting point of tantalum is very high, exceeded only by that of tungsten and rhenium.



*The melting point of tantalum is 2996 °C; boiling point is 5425 +/- 100 °C; specific gravity is 16.654; valence is usually 5, but may be 2, 3, or 4



Coltan Typical Applications:



a) 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.



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



c) 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



Coltan Standard Packaging:



1) 50 lbs. net bags



2) Bulk bags
