ʻO ka maʻiʻo obariumi ka lepo o ka honua he 0.05%. ʻO nā minelala maʻamau ma ke ʻano he barite (barium sulfate) a me witherite (barium carbonate). Hoʻohana nui ʻia ka Barium i nā mea uila, keramika, lāʻau lapaʻau, petroleum a me nā ʻano ʻē aʻe.

1.ʻOihana uila
ʻO kekahi o ka hoʻohana nui ʻana o ka barium ma ke ʻano he kiʻi e hoʻoneʻe i ke kinoea mai nā paipu māmā a me nā paipu kiʻi. Hoʻohana ʻia ia ma ke ʻano o kahi kiʻiʻoniʻoni evaporative getter, a ʻo kāna hana ka hana ʻana i nā pūhui kemika me ke kinoea a puni i loko o ka hāmeʻa e pale ai i ka cathode oxide i loko o nā paipu electron he nui mai ka hana ʻana me nā kinoea ʻino a me ka hana ʻino.
ʻO ka Barium aluminum nickel getter kahi mea evaporative maʻamau, i hoʻohana nui ʻia i nā paipu hoʻoili mana like ʻole, nā oscillator tubes, nā pahu kamera, nā kiʻi kiʻi, nā ʻili o ka lā a me nā mea hana ʻē aʻe. Hoʻohana kekahi mau paipu kiʻi i nā kiʻi alumini barium nitrided, nāna e hoʻokuʻu i ka nui o ka nitrogen i loko o ka hopena exothermic evaporative. Ke hoʻoheheʻe ka nui o ka barium, ma muli o ka hui ʻana me nā molekala nitrogen, ʻaʻole pili ka kiʻi barium getter i ka pale a i ʻole ka pale huna akā e hōʻuluʻulu a puni ka ʻāʻī o ka paipu, ʻaʻole wale ka hana getter maikaʻi, akā hoʻomaikaʻi hoʻi i ka ʻōlinolino. ka pale.
2.ʻoihana seramika
Hiki ke hoʻohana ʻia ka Barium carbonate e like me ka ipu lepo. Ke hoʻokomo ʻia ka barium carbonate i loko o ka aniani, e lilo ia i ʻulaʻula a me ka poni.
ʻO Barium titanate ka mea kumu matrix raw material o titanate series electronic ceramics a ua ʻike ʻia ʻo ia ke kia o ka ʻoihana seramika uila. Barium titanate he kiʻekiʻe dielectric mau, haʻahaʻa dielectric poho, maikaʻi ferroelectric, piezoelectric, puʻe kū'ē a me ka insulation waiwai, a ua hoʻohana nui 'ia i loko o ka ceramic sensitive mea, oi aku ka maikaʻi wela coefficient thermistors (PTC), multilayer ceramic capacitors (MLCCS), thermoelectric mau mea, piezoelectric ceramics, sonar, infrared radiation detection elements, crystal ceramic capacitors, nā paneli hōʻike electro-optical, nā mea hoʻomanaʻo, nā mea hoʻohui polymer-based a me nā uhi.
3. ʻOihana ahi ahi
ʻO nā paʻakai barium (e like me ka barium nitrate) e puhi me kahi ʻōmaʻomaʻo ʻōmaʻomaʻo-melemele ʻōmaʻomaʻo a hoʻohana pinepine ʻia e hana i nā mea ahi a me nā lapalapa. Hana ʻia nā mea ahi keʻokeʻo a mākou e ʻike nei me ka barium oxide.
4.ʻOiʻaʻaila
ʻO ka pauka Baryte, i ʻike ʻia ʻo ka barium sulfate maoli, ua hoʻohana nui ʻia ma ke ʻano he mea kaupaona no ka ʻaila a me ka lepo wili kino. ʻO ka hoʻohui ʻana i ka pauka barite i ka lepo hiki ke hoʻonui i ka ʻumekaumaha kikoʻī o ka lepo, ke kaulike i ke kaumaha o ka lepo me ka ʻaila ma lalo o ka lepo a me ke kaomi kinoea, a pēlā e pale ai i nā pōʻino.
5.Pest control
ʻO ka Barium carbonate he pauka keʻokeʻo ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai akā hiki ke hoʻoheheʻe ʻia i ka waikawa. He mea ʻawaʻawa a hoʻohana pinepine ʻia e like me ka lāʻau make ʻiole. Hiki i ka Barium carbonate ke hana me ka waika hydrochloric i loko o ka wai ʻōpū e hoʻokuʻu i nā ion barium ʻona, e hoʻoulu ai i nā hopena ʻona. No laila, pono mākou e pale i ka ʻai ʻole ʻana i ke ola o kēlā me kēia lā.
6.ʻoihana lapaʻau
ʻO ka Barium sulfate kahi pauka keʻokeʻo ʻole a ʻono ʻole ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai ʻaʻole i loko o ka waikawa a i ʻole ka alkali, no laila ʻaʻole ia e hana i nā ion barium ʻona. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he lāʻau kōkua no nā hoʻokolohua X-ray no nā hoʻokolokolo kiʻi gastrointestinal, i ʻike mau ʻia ʻo "barium meal imaging".
Hoʻohana nā hoʻokolohua radiological i ka barium sulfate no ka mea hiki iā ia ke komo i nā kukui X i loko o ka ʻōpū o ka ʻōpū e hoʻomohala ai. ʻAʻohe hopena pharmacological iā ia iho a e hoʻokuʻu ʻia mai ke kino ma hope o ka ʻai ʻana.
Hōʻike kēia mau noi i ka versatility ometala bariuma me kona koʻikoʻi i ka ʻoihana, ʻoi aku hoʻi i nā ʻoihana uila a me nā ʻoihana kemika. ʻO nā waiwai kino a me nā kemika kūʻokoʻa o ka metala barium e hana ia i mea koʻikoʻi i nā ʻoihana he nui.
