Tantal (Ta)
Opdaget i 1802 forekommer tantal hovedsageligt i columbit-tantalit-mineraler. Den første relativt rene duktile tantal blev produceret i 1903.
Tantal er gråt, tungt og meget hårdt. I ren form er det duktilt og, når det formes til tråd, bruges det som et filament til fordampning af aluminium og andre metaller. Det bruges til at øge smeltepunkter, styrke og duktilitet af legeringer. Naturlig tantal har to isotoper; i alt 25 kendes.
Dette element bruges også i elektrolytiske kondensatorer, vakuumovnsdele, kemisk procesudstyr, atomreaktorer, fly- og missildele og kirurgiske apparater.
