Pauka Boron

He mea metalloid ka Boron, nona nā allotropes ʻelua, ʻo ka boron amorphous a me ka boron crystalline. He pauka ʻeleʻele ka boron amorphous ʻoiai he kālā a ʻeleʻele paha ka boron crystalline. He boron maʻemaʻe kiʻekiʻe nā granules boron crystalline a me nā ʻāpana boron, paʻakikī loa, a he alakaʻi maikaʻi ʻole i ka mahana o ka lumi.

Boron kristal

ʻO ke ʻano kristal o ka boron crystalline he β-ʻano nui, kahi i hana ʻia mai ke ʻano β a me ke ʻano γ i loko o kahi cube e hana i kahi ʻano kristal paʻa. Ma ke ʻano he boron crystalline kūlohelohe, ʻoi aku kona nui ma mua o 80%. ʻO ke kala maʻamau he pauka hina-ʻeleʻele a i ʻole nā ​​​​​​ʻāpana ʻano ʻokoʻa ʻole. ʻO ka nui o nā ʻāpana maʻamau o ka pauka boron crystalline i hoʻomohala ʻia a hoʻopilikino ʻia e kā mākou hui he 15-60μm; ʻo ka nui o nā ʻāpana maʻamau o nā ʻāpana boron crystalline he 1-10mm (hiki ke hoʻopilikino ʻia ka nui o nā ʻāpana kūikawā e like me nā pono o ka mea kūʻai aku). Ma ke ʻano laulā, ua māhele ʻia i ʻelima mau kikoʻī e like me ka maʻemaʻe: 2N, 3N, 4N, 5N, a me 6N.

Nā kikoʻī ʻoihana Crystal Boron

Pūʻolo: Hoʻopaʻa pinepine ʻia i loko o nā ʻōmole polytetrafluoroethylene a hoʻopaʻa ʻia me ke kinoea inert, me nā kikoʻī o 50g / 100g / ʻōmole;

Boron Amorphous

Ua kapa ʻia hoʻi ʻo Amorphous boron he boron non-crystalline. ʻO kona ʻano kristal he ʻano α, no ke ʻano kristal tetragonal, a ʻo kona kala he ʻeleʻele brown a melemele iki paha. ʻO ka pauka boron amorphous i hoʻomohala ʻia a hoʻopilikino ʻia e kā mākou hui he huahana kiʻekiʻe. Ma hope o ka hana hohonu, hiki i ka ʻike boron ke hiki i 99%, 99.9%; ʻo ka nui o ka ʻāpana maʻamau ʻo D50≤2μm; e like me nā koi kūikawā o ka nui o ka ʻāpana o nā mea kūʻai aku, hiki ke hana ʻia a hoʻopilikino ʻia ka pauka sub-nanometer (≤500nm).

Nā Kikoʻī ʻOihana Boron Amorphous

Pūʻolo: Ma keʻano laulā, ua hoʻopili ʻia i loko o nā ʻeke pepa alumini vacuum me nā kikoʻī o 500g / 1kg (ʻaʻole i hoʻomaʻemaʻe ʻia ka pauka nano);

ʻIsotope ¹¹B

ʻO ka nui maoli o ka isotope ¹¹B he 80.22%, a he dopant a me ka diffuser kiʻekiʻe ia no nā mea ʻāpana semiconductor. Ma ke ʻano he dopant, hiki iā ¹¹B ke hana i nā ion silicon i hoʻonohonoho paʻa ʻia, kahi i hoʻohana ʻia e hana i nā kaapuni i hoʻohui ʻia a me nā microchips kiʻekiʻe, a he hopena maikaʻi hoʻi i ka hoʻomaikaʻi ʻana i ka hiki ke pale aku i ka radiation interference o nā mea semiconductor. ʻO ka isotope ¹¹B i hoʻomohala ʻia a hoʻopilikino ʻia e kā mākou hui he isotope kristal ʻano β cubic me ka maʻemaʻe kiʻekiʻe a me ka nui kiʻekiʻe, a he mea maka koʻikoʻi ia no nā ʻāpana kiʻekiʻe.

ʻO ka kikoʻī ʻoihana ʻo Isotope¹¹B

Pūʻolo: Hoʻopaʻa ʻia i loko o ka ʻōmole polytetrafluoroethylene, piha i ka pale kinoea inert, 50g/ʻōmole;

ʻIsotope ¹ºB

ʻO ka nui maoli o ka isotope ¹ºB he 19.78%, he mea pale nukelea maikaʻi loa ia, ʻoi aku hoʻi me ka hopena omo maikaʻi ma nā neutrons. ʻO ia kekahi o nā mea maka e pono ai i nā lako ʻoihana nukelea. ʻO ka isotope ¹ºB i hoʻomohala ʻia a hana ʻia e kā mākou hui no ka isotope kristal ʻano β cubic, nona nā pono o ka maʻemaʻe kiʻekiʻe, ka nui kiʻekiʻe a me ka hui maʻalahi me nā metala. ʻO ia ka mea maka nui o nā lako kūikawā.

ʻO ka kikoʻī ʻoihana ʻo Isotope¹ºB

Pūʻolo: Hoʻopaʻa ʻia i loko o ka ʻōmole polytetrafluoroethylene, piha i ka pale kinoea inert, 50g/ʻōmole;

He aha ka mea e hoʻohana ʻia ai ʻo Amorphous boron, Boron powder a me Natural boron?

Nui nā noi no ka boron Amorphous, ka pauka Boron a me ka boron kūlohelohe. Hoʻohana ʻia lākou i ka metallurgy, nā mea uila, nā lāʻau lapaʻau, nā keramika, ka ʻoihana nukelea, ka ʻoihana kemika a me nā ʻoihana ʻē aʻe.

1. Hoʻohana ʻia ka boron amorphous i ka ʻoihana kaʻa ma ke ʻano he mea hoʻā ahi i nā ʻeke ea a me nā mea hoʻopaʻa kāʻei. Hoʻohana ʻia ka boron amorphous i nā pyrotechnics a me nā rockets ma ke ʻano he mea hoʻohui i nā lapalapa ahi, nā mea hoʻā ahi a me nā mea hoʻopaneʻe, nā wahie propellant paʻa, a me nā mea pahū. Hāʻawi ia i nā lapalapa ahi i kahi kala ʻōmaʻomaʻo ʻokoʻa.

2. Hana ʻia ka boron kūlohelohe me ʻelua isotopes paʻa, ʻo kekahi o ia mau mea (boron-10) he nui nā hoʻohana ma ke ʻano he mea hopu neutron. Hoʻohana ʻia ia ma ke ʻano he mea hoʻomoʻa neutron i nā kaohi reactor nukelea, a me ka hoʻopaʻakikī ʻana i ka radiation.

3. Hoʻohana ʻia ka boron Elemental ma ke ʻano he dopant i ka ʻoihana semiconductor, ʻoiai ʻo nā hui boron e pāʻani i nā kuleana koʻikoʻi ma ke ʻano he mau mea kūkulu māmā, nā insecticides a me nā preservatives, a me nā reagents no ka synthesis kemika.

4. ʻO ka pauka Boron kahi ʻano wahie metala me nā waiwai calorific gravimetric a me volumetric kiʻekiʻe, kahi i hoʻohana nui ʻia i nā kahua koa e like me nā propellants paʻa, nā mea pahū ikehu kiʻekiʻe, a me nā pyrotechnics. A ua hoʻemi nui ʻia ka mahana hoʻā ʻana o ka pauka boron ma muli o kona ʻano ʻokoʻa a me ka nui o ka ʻili kikoʻī;

5. Hoʻohana ʻia ka pauka Boron ma ke ʻano he ʻāpana alloy i nā huahana metala kūikawā e hana i nā alloys a hoʻomaikaʻi i nā waiwai mechanical o nā metala. Hiki ke hoʻohana ʻia e uhi i nā uea tungsten a i ʻole e like me nā fillaments i nā composites me nā metala a i ʻole nā ​​​​ceramic. Hoʻohana pinepine ʻia ʻo Boron i nā alloys hana kūikawā e hoʻopaʻakikī i nā metala ʻē aʻe, ʻo ia hoʻi nā alloys brazing wela kiʻekiʻe.

6. Hoʻohana ʻia ka pauka Boron ma ke ʻano he deoxidizer i ka hoʻoheheʻe ʻana i ke keleawe ʻole oxygen. Hoʻohui ʻia kahi liʻiliʻi o ka pauka boron i ka wā o ke kaʻina hana hoʻoheheʻe metala. Ma kekahi ʻaoʻao, hoʻohana ʻia ia ma ke ʻano he deoxidizer e pale aku i ka oxidized o ka metala i ka mahana kiʻekiʻe. Hoʻohana ʻia ka pauka Boron ma ke ʻano he mea hoʻohui no nā piliki magnesia-carbon i hoʻohana ʻia i loko o nā umu wela kiʻekiʻe no ka hana kila;

7. He mea pono nō hoʻi nā Pauka Boron i kekahi noi kahi e makemake ʻia ai nā wahi ʻili kiʻekiʻe e like me ka mālama ʻana i ka wai a me nā noi cell wahie a me ka lā. Hoʻopuka pū nā Nanoparticles i nā wahi ʻili kiʻekiʻe loa.

8. He mea nui nō hoʻi ka pauka Boron no ka hana ʻana i ka boron halide maʻemaʻe kiʻekiʻe, a me nā mea ʻē aʻe i hui ʻia me ka boron; Hiki ke hoʻohana ʻia ka pauka Boron ma ke ʻano he kōkua hoʻoheheʻe; Hoʻohana ʻia ka pauka Boron ma ke ʻano he mea hoʻomaka no nā ʻeke ea kaʻa;
