Za ine Tantalum
Tantalum ndi yolimba, yofiira-yenyezimira, yowala yokhala ndi gawo lachitatu lotentha kwambiri.Izi ndi zosatheka kulimbana ndi mankhwala osokoneza bongo pansi pa 150 ° C C ndi biocompatible.
Kugwiritsa ntchito & Maphunziro
Ma capacitors amagetsi (mafoni a m'manja, makompyuta), ma implantes a chithandizo chamankhwala, ma components a injini ya jet, ndi zida za chikhalidwe.
Fun Facts
Tantalum capacitors ndi m'madera ambiri a smartphone.Mining wa coltan (tantalum ore) wakhala wogwirizana ndi nkhondo ku Congo.
