ʻO ka Tantalum kahi mea kemika me ka hōʻailona Ta a me ka helu ʻātoma 73. Ua haku ʻia me nā ʻātoma tantalum me 73 protons i loko o ka nucleus. ʻO ka Tantalum kahi metala hoʻololi kakaʻikahi, paʻakikī, polū-hina, ʻālohilohi i kūpaʻa loa i ka ʻino. Hoʻohui pinepine ʻia me nā metala ʻē aʻe e hoʻomaikaʻi ai i kāna mau ʻano mechanical a hoʻohana ʻia i nā ʻano hana like ʻole, me ka uila, aerospace a me nā mea lapaʻau.

Loaʻa i ka Tantalum kekahi mau waiwai kemika kaulana:

1. Ke kū'ē i ka corrosion: ʻO ka Tantalum ke kū'ē i ka corrosion, kūpono ia no ka hoʻohanaʻana i nā wahi corrosive e like me ka hana kemika a me nā implants.

2. Kiʻekiʻe heheʻe helu: Tantalum he kiʻekiʻe loa hehee ai wahi, ma luna o 3000 degere Celsius, i mea e pono ai no ke kiʻekiʻe wela noi.

3. Inertness: ʻAʻole inert ʻo Tantalum, ʻo ia hoʻi, ʻaʻole maʻalahi ia e hana me nā mea ʻē aʻe a i ʻole nā ​​​​hui ma lalo o nā kūlana maʻamau.

4. Ke kū'ē o ka oxidation: Hoʻokumu ʻo Tantalum i kahi ʻāpana oxide pale i ka wā e ʻike ʻia ai i ka ea, e hāʻawi hou ana i ke kūʻē i ka corrosion.

Hoʻolilo kēia mau waiwai i ka tantalum i mea waiwai i nā ʻano hana ʻenehana a me nā ʻenehana.

Hoʻokumu ʻia ka Tantalum ma o nā kaʻina hana honua. Loaʻa pinepine ʻia me nā minerala ʻē aʻe, e like me columbite-tantalite (coltan), a lawe pinepine ʻia ma ke ʻano he huahana o ka ʻeli ʻana o nā metala ʻē aʻe, e like me ka tin. Loaʻa ka Tantalum i loko o nā pegmatites, ʻo ia nā pōhaku igneous coarse-grained i loaʻa pinepine i nā kiʻekiʻe kiʻekiʻe o nā mea laʻa.

ʻO ka hoʻokumu ʻana o nā waihona tantalum e pili ana i ka crystallization a me ka hoʻoluʻu ʻana o ka pele a me ka neʻe ʻana o nā minerala i loko o ka tantalum ma o nā kaʻina hana honua e like me ka hydrothermal activity a me ka weathering. I ka hala ʻana o ka manawa, hana kēia mau kaʻina hana i ka tantalum-rich ores i hiki ke ʻeli ʻia a hana ʻia e unuhi i ka tantalum no nā ʻano hana ʻenehana a me nā ʻenehana.

ʻAʻole maʻamau ʻo Tantalum. Manaʻo ʻia ʻo ia he non-magnetic a he haʻahaʻa haʻahaʻa haʻahaʻa. Hoʻohana kēia waiwai i ka tantalum i nā noi kahi e koi ʻia ai ka hana non-magnetic, e like me nā mea uila a me nā mea lapaʻau.
