E aʻo e pili ana iā Bismuth

ʻO Bismuth he metala keʻokeʻo keʻokeʻo a hiki i ka ʻulaʻula a palupalu a maʻalahi hoʻi e wāwahi. ʻAno paʻa kona mau waiwai kemika. Aia ʻo Bismuth ma ke ʻano ma ke ʻano metala manuahi a me nā minela.
1. [Nature]
ʻO ka bismuth maʻemaʻe he metala palupalu, aʻo ka bismuth haumia he palupalu. Ua kūpaʻa ma ka lumi wela. ʻO kāna ores nui he bismuthinite (Bi2S5) a me bismuth ocher (Bi2o5). Hoʻonui ka bismuth wai ke paʻa.
He palupalu a maikaʻi ʻole ka uila a me ka wela. ʻO Bismuth selenide a me telluride nā waiwai semiconductor.
ʻO ka metala Bismuth he keʻokeʻo keʻokeʻo keʻokeʻo (ʻulaʻula) a hiki i ka ʻulaʻula melemele māmā, palupalu a maʻalahi ke ʻoki ʻia; ma ka lumi wela, ʻaʻole pane ka bismuth me ka oxygen a i ʻole ka wai a paʻa i ka lewa. Loaʻa iā ia ka hana uila a me ka thermal conductivity; Ua manaʻo mua ʻia ʻo bismuth ka mea paʻa loa me ka nui o ka nui atomic pili, akā i ka makahiki 2003, ua ʻike ʻia he radioactive nāwaliwali ka bismuth a hiki ke pohō i loko o ka thallium-205 ma o ka palaho α. ʻO ka hapalua o kona ola ma kahi o 1.9X10^19 makahiki, ʻo ia hoʻi he 1 biliona manawa o ke ola o ke ao holoʻokoʻa.

semiconductor
Hoʻohana ʻia nā ʻāpana Semiconductor e ka hui ʻana i ka bismuth maʻemaʻe kiʻekiʻe me tellurium, selenium, antimony, etc. Hoʻohana ʻia lākou e hoʻohui i nā ea a me nā pahu hau. Hiki ke hoʻohana ʻia ka bismuth sulfide no ka hana ʻana i nā photoresistors i nā polokalamu photoelectric e hoʻonui i ka naʻau i ka ʻāpana spectrum ʻike ʻia.
ʻOihana Nukelea
Hoʻohana ʻia ka bismuth hoʻomaʻemaʻe kiʻekiʻe ma ke ʻano he mea lawe wela a i ʻole ka mea hoʻomaha i loko o nā reactors ʻoihana nuklea a ma ke ʻano he mea no ka pale ʻana i nā mea hoʻoheheʻe atomika.
ʻElepona Seramika
ʻO nā mea uila uila e loaʻa ana i ka Bismuth e like me ka bismuth germanate crystals he ʻano hou o nā kristal scintillating i hoʻohana ʻia i ka hana ʻana i nā mea ʻike uila nuklea , X-ray tomography scanners , electro-optics, piezoelectric lasers a me nā mea hana ʻē aʻe; bismuth calcium vanadium (pomegranate ferrite he mea koʻikoʻi microwave gyromagnetic mea a me nā mea hoʻopaʻa magnetic), bismuth oxide-doped zinc oxide varistors , bismuth-containing boundary layer high-frequency ceramic capacitors , tin-bismuth mau magnet , bismuth titanate ceramics a me ka pauka, bismuth silicate crystals , bismuth-containing fusible glass and more than 10 other materials has also begined to use in the industry.
Laau lapaau
Loaʻa i nā pūhui Bismuth nā hopena o ka astringency, antidiarrhea, a me ka mālama ʻana i ka dyspepsia gastrointestinal. Hoʻohana ʻia ka bismuth subcarbonate, bismuth subnitrate, a me ka pālolo bismuth subrubberate e hana i nā lāʻau lapaʻau ʻōpū. Hoʻohana ʻia ka hopena astringent o nā lāʻau bismuth i ka ʻoki ʻana e mālama i ka trauma a hoʻōki i ke koko. I loko o ka radiotherapy, hoʻohana ʻia nā ʻāpana bismuth ma kahi o ka alumini no ka hana ʻana i nā papa pale no ka poʻe maʻi e pale aku i nā ʻāpana ʻē aʻe o ke kino mai ka ʻike ʻana i ka radiation. Me ka ulu ʻana o nā lāʻau bismuth, ua ʻike ʻia aia kekahi mau lāʻau bismuth i nā hopena anti-cancer.
Mea hoʻohui metala
ʻO ka hoʻohui ʻana i ka nui o ka bismuth i ke kila hiki ke hoʻomaikaʻi i ka hana ʻana o ke kila, a ʻo ka hoʻohui ʻana i ka nui o ka bismuth i ka hao hoʻoheheʻe malleable hiki ke loaʻa iā ia nā waiwai e like me ke kila kila.
