ʻO ka Tantalum he metala koʻikoʻi, ductile kaumaha, ʻano like loa me ka niobium.E like me kēia, hana maʻalahi ia i kahi papa pale oxide, kahi e pale ai i ka corrosion.He kila hina hina kona waihoʻoluʻu me ka poni a me ka poni.Hoʻohana ʻia ka hapa nui o ka tantalum no nā capacitors liʻiliʻi me ka mana kiʻekiʻe, e like me nā mea ma nā kelepona.No ka mea, ʻaʻohe mea ʻawaʻawa a kūpono hoʻi me ke kino, hoʻohana ʻia i ka lāʻau lapaʻau no nā prostheses a me nā mea hana.ʻO Tantalum ka mea paʻa paʻa loa i ke ao holoʻokoʻa, akā naʻe, he nui nā waihona o ka Honua.ʻO ka Tantalum carbide (TaC) a me ka tantalum hafnium carbide (Ta4HfC5) he paʻakikī loa a paʻa hoʻi.
