Pilikino metala pauda waiwai

ʻO ka pauka metala silikon he mea maʻalahi me ka nui o nā noi i nā ʻoihana like ʻole. ʻO nā waiwai kūʻokoʻa o ka pauka metala silicon he mea waiwai nui ia no nā huahana a me nā kaʻina hana. Ma kēia ʻatikala, e ʻimi mākou i nā waiwai koʻikoʻi o ka pauka metala silika a e ʻimi i kāna mau noi like ʻole.

Ka Hui Kimia a me ka Maemae

ʻO ka pauka metala silikoni ka mea nui i haku ʻia me ka silika elemental, ʻo ia ka lua o ka mea nui loa i loko o ka ʻōpala o ka Honua ma hope o ka oxygen. Hiki ke ʻokoʻa ka maʻemaʻe o ka pauka metala silicon, me nā māka maʻemaʻe kiʻekiʻe e makemake nui ʻia no nā noi kūikawā. ʻO ka maʻamau,pauda metala silikahiki ke loaʻa ka maʻemaʻe mai ka 95% a i ka 99.9999%, ma muli o ke kaʻina hana a me ka hoʻohana i manaʻo ʻia.

Hōʻike pinepine ʻia ka pauka metala silikon i nā ʻāpana polyhedral like ʻole a i ʻole nā ​​ʻāpana spherical. ʻO ka hāʻawi ʻana i ka nui o nā ʻāpana mai nā nanometers a i nā micrometers, ma muli o ke kaʻina hoʻomākaukau a me nā koi noi. ʻO ka hāʻawi ʻana i ka nui o ka nui o ka pauka silicon kalepa ma waena o 0.1-100 microns.

Ka nui a me ka laha ana

ʻO ka nui o ka ʻāpana a me ka hāʻawi ʻana i ka pauka metala silicon he mau hiʻohiʻona koʻikoʻi e hoʻoikaika i kāna hana a kūpono no nā noi like ʻole. Hiki ke hana ʻia ka pauka metala silika me ka nui o ka nui o nā ʻāpana, mai nā ʻāpana micron-scale maikaʻi a hiki i ka coarser, nā ʻāpana nui. Hiki ke hoʻolikelike ʻia ka nui o ka nui o ka particle e hoʻokō i nā koi kikoʻī, e like me ka hoʻomaikaʻi ʻana i ka flowability, ka hoʻonui ʻana i ka ʻili no nā hopena kemika, a i ʻole ka hoʻonui ʻana i ka packing density i nā kaʻina hana like ʻole.

Morphology a me ka Ili

Hiki ke ʻano like ʻole ke ʻano o ke kino, a i ʻole ke ʻano kino, o nā ʻāpana pauka metala silika. ʻO kekahi mau morphologies maʻamau e pili ana i nā ʻano spherical, angular, a i ʻole ʻano like ʻole. He waiwai ko'iko'i ka ili o ka pauka metala silika, no ka mea, pili ia i ka reactivity, adsorption, a me nā waiwai catalytic. Hiki ke hoʻonui i ka pono o nā kaʻina hana like ʻole, e like me ka hopena kemika, catalysis, a me ka mālama ʻana i ka ikehu.

Waiwai wela

Hōʻike ka pauka metala silikoni i nā waiwai wela maikaʻi loa, me ka hoʻokō wela kiʻekiʻe, ka hoʻonui haʻahaʻa wela, a me ka helu heheʻe kiʻekiʻe. Hana kēia mau hiʻohiʻonametala silikaʻO ka pauka he mea waiwai i nā noi e koi ana i ka hoʻololi wela kūpono, ka hoʻokele wela, a i ʻole ke kūʻē ʻana i nā kaiapuni wela kiʻekiʻe.

Na Waiwai Uila

Loaʻa i ka pauka metala silikoni nā waiwai uila, me ka conductivity uila kiʻekiʻe a me ke ʻano semiconductor-like. Hoʻohana ʻia kēia mau waiwai i nā noi uila a me ka ikehu, e like me nā cell solar, nā mea semiconductor, a me nā ʻōnaehana mālama ikehu.

Na Waiwai Mechanical

Hiki ke hoʻopili ʻia nā ʻano mechanical o ka pauka metala silicon, e like me ka paʻakikī, ka ikaika, a me ke kūpaʻa ʻana i ka lole, ma o nā ʻano hana hana like ʻole. Pono kēia mau waiwai i nā noi kahi i hoʻohana ʻia ai ka pauka metala silika ma ke ʻano he mea hoʻoikaika a i ʻole ka hana ʻana i nā composites holomua.

Nā noi o ka pauka metala silika

ʻIke ʻia ka pauka metala silikon i kahi ākea o nā noi ma nā ʻoihana like ʻole, me:

a. Electronics a me Semiconductors: He mea koʻikoʻi ka pauka metala silikon no ka hana ʻana i nā wafer silika, nā pūnaewele lā, nā kaapuni i hoʻohui ʻia, a me nā mea uila ʻē aʻe.

b. Nā Hana Kemika a me Catalytic: Hoʻohana ʻia ka pauka metala silika ma ke ʻano he catalyst, absorbent, a i ʻole reactant i nā kaʻina hana kemika, me ka hana ʻana i nā silicones, silanes, a me nā mea hoʻohui ʻē aʻe.

c. Metallurgy and Composite Materials: Hoʻohana ʻia ka pauka metala silika ma ke ʻano he mea hoʻohuihui i ka hana ʻana i nā ʻāpana metala like ʻole, a me kahi mea hoʻoikaika i nā composites holomua.

d. ʻO ka mālama ʻana i ka ikehu a me ka hoʻololi ʻana: Hoʻohana ʻia ka pauka metala silika i ka hana ʻana i nā pākahi lithium-ion, nā pānaʻi sodium-ion, a me nā mea mālama ikehu ʻē aʻe, a me ka hana ʻana i nā cell photovoltaic no ka hoʻololi ʻana i ka ikehu o ka lā.

e. ʻO nā mea hoʻomaʻemaʻe a me nā mea hana ʻino:ʻO ka pauka metala silikahe mea nui ia i ka hana ʻana i nā ceramics kiʻekiʻe, refractory, a me nā mea holomua ʻē aʻe e hiki ke kū i nā wela wela a me nā wahi paʻakikī.

f. Abrasive a me ka Polishing: ʻO ka paʻakikī a me ka angular morphology o ka pauka metala silicon e lilo ia i mea kūpono no ka hoʻohana ʻana i nā noi abrasive a me ka polishing, e like me ka hana ʻana i ka sandpaper, nā pūhui polishing, a me nā huahana hoʻopau ʻili.

ʻO ka pauka metala silikon he mea maʻalahi a koʻikoʻi me ka nui o nā waiwai a me nā noi. ʻO kona ʻano kemika, ka nui o ka ʻāpana, ka morphology, ka wela, ka uila, a me nā waiwai mechanical e lilo ia i mea waiwai nui i nā ʻoihana he nui, mai ka uila a me ka ikehu a hiki i ka metallurgy a me nā ceramics. Ke hoʻomau nei ka ʻenehana i ka holomua, e piʻi aʻe ka noi no ka pauka metala silicon kiʻekiʻe, e hoʻokau hou i ka hana hou a me ka hoʻomohala ʻana i ka hana a me ka hoʻohana ʻana i kēia mea kupaianaha.
