I-Tantalum iyinsimbi eqinile, ene-ductile, efana kakhulu ne-niobium ngamakhemikhali.Njengalokhu, yenza kalula ungqimba lwe-oxide oluvikelayo, okwenza lukwazi ukumelana nokugqwala.Umbala wayo umpunga wensimbi ngokuthinta kancane okuluhlaza okwesibhakabhaka nokunsomi.Iningi le-tantalum lisetshenziselwa ama-capacitor amancane anamandla aphezulu, njengalawo akumaselula.Ngenxa yokuthi ayinabo ubuthi futhi ihambisana kahle nomzimba, isetshenziswa kwezokwelapha izitho zokwenziwa nezinsimbi.I-Tantalum iyisici esiyivelakancane esizinzile endaweni yonke, noma kunjalo, uMhlaba unemali enkulu.I-Tantalum carbide (TaC) kanye ne-tantalum hafnium carbide (Ta4HfC5) ziqinile kakhulu futhi zihlala zisebenza.
