Tantalum chinhu chemakemikari chine chiratidzo Ta uye nhamba yeatomu 73. Inoumbwa nemaatomu etantalum ane mapurotoni makumi manomwe nematatu mukati memwoyo. Tantalum isimbi isingawanzoitiki, yakaoma, yebhuruu-grey, inopenya inoshingirira mukuora. Inowanzo sanganiswa nedzimwe simbi kuti ivandudze midziyo yayo uye inoshandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira zvemagetsi, aerospace uye zvigadzirwa zvekurapa.

Tantalum ine akati wandei anozivikanwa makemikari zvimiro:

1. Corrosion resistance: Tantalum inoshingirira mukuora zvakanyanya, ichiita kuti ive yakakodzera kushandiswa munzvimbo dzine ngura dzakadai semakemikari ekugadzira uye kudyara.

2. High melting point: Tantalum ine nzvimbo yakanyanyisa kunyungudika, inodarika 3000 madhigirii celsius, izvo zvinoita kuti ibatsire pakupisa tembiricha.

3. Inertness: Tantalum iinert inert, zvinoreva kuti haiite nyore nemamwe maelementi kana makomisheni pasi pemamiriro akajairika.

4. Oxidation resistance: Tantalum inoumba chidziviriro oxide layer kana yaiswa mumhepo, ichienderera mberi ichipa kurwisana nekuora.

Izvi zvivakwa zvinoita kuti tantalum ive yakakosha muakasiyana maindasitiri uye tekinoroji mashandisirwo.

Tantalum inoumbwa kuburikidza nemhando dzakasiyana dze geological process. Inowanzo kuwanikwa pamwe chete nemamwe maminerari, akadai secolumbite-tantalite (coltan), uye anowanzo kutorwa sechigadzirwa chemigodhi yemamwe simbi, senge tini. Tantalum inowanikwa mumapegmatites, ari matombo akaomesesa-grained igneous anowanzo aine huwandu hwakanyanya hwezvinhu zvisingawanzo.

Kuumbwa kwetantalum deposits kunosanganisira crystallization uye kutonhora kwelava uye kuteedzera kunotevera kwetantalum-ine zvicherwa kuburikidza ne geological process senge hydrothermal chiitiko uye mamiriro ekunze. Nekufamba kwenguva, maitiro aya anoumba tantalum-rich ores inogona kucherwa uye kugadziriswa kuti ibvise tantalum kune akasiyana maindasitiri uye ehunyanzvi mashandisirwo.

Tantalum haisi yemagineti chaiyo. Inofungidzirwa kunge isiri-magnetic uye ine yakaderera magineti permeability. Ichi chivakwa chinoita kuti tantalum ibatsire mukushandisa uko kusiri-magineti maitiro anodiwa, senge mune zvemagetsi zvikamu uye zvigadzirwa zvekurapa.
