Chemical Properties:
Formula: (Fe, Mn)Ta₂O₆ Oxidation States: Tantalum in tantalite is typically in the +5 oxidation state. Solubility: Insoluble in water, but can be dissolved in hydrofluoric acid.
Tantalite (Fe, Mn)Ta₂O₆
Tantalite is a heavy, dark, lustrous mineral that is the primary source of the chemical element tantalum. It belongs to the oxide minerals group and is often found in granitic pegmatites and placer deposits.
Did You Know? Tantalite is chemically similar to columbite, and the two are often grouped together as coltan or “columbite-tantalite.”
Purity and Supply:
Our tantalite ore meets the strictest industrial standards.
We are able to supply any quantity needed.
Common Applications:
AlloysTantalum extracted from tantalite is used in alloys for its strength and high melting points.
Electronics:Used in capacitors and high-power resistors in electronic devices.
Aerospace:Employed in the aerospace industry for its high-temperature resistance.
Medical:Used in surgical steel and other medical applications due to its non-reactive and non-irritating properties.
Associated Minerals:
Tantalite is often found with minerals such as columbite, beryl, and cassiterite.
Purity:
Our tantalite is free from impurities such as:
Iron: Can affect the strength and durability of tantalum alloys.Manganese: Alters the electrical and thermal properties.
Silicon: Can impact the hardness and brittleness.
Magnesium: Affects the melting point and alloying behavior.
