Tantalum Wire

• Raw Material Acquisition
  • Source tantalum ore, mainly tantalite ((Fe, Mn) [(Nb,Ta)O3]2), from certified mines to ensure quality and ethical mining practices.
• Ore Processing
  • Crush and grind the tantalum ore.
  • Subject the ore to a series of flotation processes to separate tantalum from other elements.
  • Refine the obtained concentrates to reach an approximate content of 70% (Ta, Nb)2O5.
• Conversion to K2TaF7
  • Dissolve the concentrate in a mixture of hydrofluoric and sulfuric acid.
  • Convert the resultant fluoride complex (TaF7) into an organic phase using a liquid extraction process.
  • Separate the organic phase from the aqueous phase.
  • Obtain potassium heptafluorotantalate (K2TaF7) by separating tantalum from the organic phase using potassium hydrogen fluoride.
• Reduction to Tantalum Powder
  • Reduce K2TaF7 with sodium in a high-temperature furnace under an inert atmosphere. This step produces pure tantalum powder.
• Powder Metallurgy
  • Ensure the powder’s purity, grain size, and morphology.
  • Bind and press the tantalum powder into billets or pre-forms.
  • Sinter the billets in a high-vacuum furnace to consolidate the powder particles.
• Wire Drawing
  • Heat the tantalum billets to improve ductility.
  • Use a series of dies to draw the tantalum into wire form, starting with larger diameters and gradually reducing to the desired wire size.
  • Regularly anneal the wire during the drawing process to maintain ductility and prevent breakage.

• Quality Control
  • Conduct in-line inspections to ensure diameter consistency.
  • Test the wire for tensile strength, elongation, and purity.
  • Conduct microscopic examinations to verify grain structure and ensure no inclusions or imperfections.
  • Use non-destructive testing, like eddy current testing, to ensure wire integrity.

• Packaging & Storage
  • Wind the wire onto spools, reels, or coils, ensuring no kinks or bends.
  • Package in moisture-proof and air-tight containers to prevent oxidation.
  • Store in a cool, dry environment until shipment or use.
