ʻO ka mōʻaukala hoʻomohala o ka metala tantalum

ʻOiai ua ʻike ʻia ka tantalum i ka hoʻomaka ʻana o ke kenekulia 19, ʻaʻole i loaʻa ka tantalum metala

hana ʻia a hiki i ka makahiki 1903, a hoʻomaka ka hana ʻana o ka tantalum i ka makahiki 1922. No laila,

ua hoʻomaka ka hoʻomohala ʻana o ka ʻoihana tantalum honua i ka makahiki 1920, a me Kina

Ua hoʻomaka ka ʻoihana tantalum i ka makahiki 1956.

ʻO ʻAmelika Hui Pū ʻIa ka ʻāina mua o ka honua e hoʻomaka i ka hana tantalum. I ka makahiki 1922,

Ua hoʻomaka ia e hana i ka tantalum metala ma kahi ʻoihana ʻenehana. ʻO Iapana a me nā mea waiwai ʻē aʻe

Ua hoʻomaka nā ʻāina āpau e hoʻomohala i ka ʻoihana tantalum i ka hopena o 1950s a i ʻole 1960s mua.

Ma hope o nā makahiki o ka hoʻomohala ʻana, ua loaʻa ka hana o ka ʻoihana tantalum i ka honua

hiki i kahi kiʻekiʻe loa. Mai ka makahiki 1990, nā mea hana nui o

ʻO nā huahana tantalum ka hui ʻo American Cabot Group (American Cabot, Japanese Showa

Cabot), German HCST Group (German HCST, American NRC, Japanese V-Tech, a

Thai TTA) a me Kina Ningxia Dongfang Tantalum Co., Ltd. ʻO nā hui nui ʻekolu

o China Industrial Co., Ltd., ka hana ʻana i nā huahana tantalum e kēia mau mea ʻekolu

ʻoi aku ka nui o nā hui ma mua o 80% o ka nui o ka honua. ʻO nā huahana, ʻenehana a me

ʻO nā lako o ka ʻoihana tantalum haole he kiʻekiʻe loa, e kūpono ana i nā pono

ka ulu wikiwiki o ka ʻepekema a me ka ʻenehana i ka honua.

Ua hoʻomaka ka ʻoihana tantalum o Kina i ka makahiki 1960. Ke hoʻohālikelike ʻia me nā ʻāina i kūkulu ʻia,

ʻO ka hoʻoheheʻe tantalum mua o Kina, ka hana ʻana a me ka pae hana, pae ʻenehana,

ʻoi aku ka maikaʻi o ka huahana. Mai ka makahiki 1990, mai ka makahiki 1995,

ʻO ka hana a me ka hoʻohana ʻana o Kina i hōʻike i ke ʻano o ka ulu wikiwiki.

I kēia lā, ua ʻike ka ʻoihana tantalum o Kina i ka hoʻololi ʻana mai ka "liʻiliʻi a i ka nui,

mai ka pūʻali koa a i ke kīwila, a mai loko a i waho", hoʻokumu i ka honua wale nō The

ʻōnaehana ʻoihana mai ka eli, ka hoʻoheheʻe ʻana, ka hana ʻana i ka noi, kiʻekiʻe, waena a

ua komo nā huahana haʻahaʻa i ka mākeke honua ma ke ʻano holoʻokoʻa. Ua loaʻa iā Kina

lilo i ke kolu o ka ʻāina nui loa ma ka honua i ka hoʻoheheʻe ʻana a me ka hana ʻana, a

ua komo i nā kūlana o nā ʻāina ʻoihana tantalum nui loa o ka honua.
