ʻOkoʻa ma waena o Silicon Carbide SiC a me Boron Carbide B4C

(Ka ʻokoʻa ma waena o Silicon Carbide SiC a me Boron Carbide B4C)

ʻO ka ʻokoʻa nui ma waena o ka silicon carbide a me ka boron carbide, ʻo ia i loko o ka silicon carbide e hoʻopaʻa ʻia kekahi ʻātoma kalapona i hoʻokahi ʻātoma kalapona, akā ma ka boron carbide ʻehā mau ʻātoma boron i hoʻokahi ʻātoma kalapona. 

ʻO Silicon carbide a me ka boron carbide nā pūhui kalapona. He mau mea paakiki loa keia mau mea elua. Loaʻa iā lākou nā waiwai kemika a me ke kino. 

He aha ka Silicon Carbide? 

ʻO Silicon carbide kahi mea semiconductor i hana ʻia me nā ʻātoma kalapona. ʻO ke ʻano kemika o ka pūhui ʻo SiC. No laila, loaʻa iā ia kahi ʻātoma silika i hoʻopaʻa ʻia i kahi ʻātoma kalapona e kahi paʻa covalent. ʻO ka mea, i ʻike ʻia ʻo emery, ʻike ʻia ma ke ʻano ma ke ʻano o ka mossanite, kahi minerala loa. No laila, hana ʻia ka silicon carbide ma ke ʻano he mea synthetic. 

ʻO 40g/mol ka nui o ka molar o ka silikon carbide. He ʻano aniani ʻeleʻele ʻeleʻele kēia mea, akā ʻaʻohe kala i kona ʻano maʻemaʻe. ʻO ke kala ʻeleʻele ma muli o ka loaʻa ʻana o ka hao ma ke ʻano he haumia. Eia kekahi, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i ka hao i hoʻoheheʻe ʻia a me ka lye. Eia naʻe, hiki iā mākou ke loaʻa ma kahi o 250 mau ʻano aniani o ka silikon carbide. Hōʻike kēia hui i ka polymorphism. Maanei, ʻo ka alpha silicon carbide ka mea maʻamau a paʻa. Hoʻokumu ia i nā mahana kiʻekiʻe loa a loaʻa kahi ʻano aniani hexagonal. 

Nui nā hoʻohana ʻana o ka silikon carbide. Hoʻohana nui ʻia no ka hana abrasive a ʻokiʻoki. He mea hoʻolālā koʻikoʻi nō hoʻi ia. E like me nā mea kaua i hui pū ʻia, nā ʻaʻahu pōkā pale ceramic, nā kiln wela kiʻekiʻe, a me nā mea ʻē aʻe.

He aha ka Boron Carbide? 

ʻO Boron carbide kahi mea paʻakikī loa i hana ʻia me ka boron a me nā ʻātoma kalapona. ʻO ke kumu kemika o kēia pūhui ʻo B4C. No laila, he ʻehā mau ʻātoma boron i hoʻopaʻa ʻia i hoʻokahi ʻātoma kalapona. ʻO ia ka lua ma mua o ke daimana a me ka cubic boron nitride i ka paʻakikī. No laila, ua kapa ʻia ʻo ia ʻo "black diamond". 

ʻO 55.25g/mol ka nui mola o ka boron carbide. Hōʻike ʻia ma ke ʻano he pauka ʻeleʻele a ʻeleʻele paha. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai. ʻIke ʻia kēia mea no kona paʻakikī kiʻekiʻe, kiʻekiʻe neutron absorption cross-section, a me ke kūpaʻa kiʻekiʻe i ka radiation ionizing. Eia kekahi, loaʻa iā ia nā waiwai semiconductor. No laila, ʻo nā waiwai uila o ka boron carbide ka nui o ka lawe ʻana. Ma keʻano laulā, he semiconductor P-type. 

ʻO Boron carbide kahi mea synthetic. Hiki ke hoʻomākaukau ʻia ma ka hoʻemi ʻana i ka boron trioxide i ka boron carbide i mua o ke kalapona. Pono ka hopena i ke kalapona a i ʻole ka magnesium ma ke ʻano he mea hoʻemi.

He aha ka ʻokoʻa ma waena o Silicon Carbide a me Boron Carbide? 

ʻO ka ʻokoʻa nui ma waena o ka silicon carbide a me ka boron carbide, ʻo ia i loko o ka silicon carbide e hoʻopaʻa ʻia kekahi ʻātoma kalapona i hoʻokahi ʻātoma kalapona, akā ma ka boron carbide ʻehā mau ʻātoma boron i hoʻokahi ʻātoma kalapona. ʻO ka carbide silikoni he aniani uliuli-ʻeleʻele, aʻo ka boron carbide he ʻeleʻele hina a ʻeleʻele paha. 

Hōʻuluʻulu ka ʻikepili ma lalo nei i nā ʻokoʻa ma waena o ka carbide silicon a me ka boron carbide.

Kumukuai SiC a me B4C

Hoʻopili ʻia ke kumukūʻai e nā kumu he nui e like me ka hoʻolako a me ka noi ma ka mākeke, nā ʻano ʻoihana, nā hana waiwai, nā manaʻo mākeke, a me nā hanana i manaʻo ʻole ʻia.

Inā ʻoe e ʻimi nei i ke kumukūʻai SiC a me B4C hou loa, hiki iā ʻoe ke hoʻouna mai iā mākou i kāu nīnau no kahi ʻōlelo kūʻai. ( [email protected] )

ʻO SiC a me B4C mea hoʻolako

ʻO RBOSCHCO kahi mea kūʻai aku a me nā mea hana mea hoʻohana i ʻoi aku ma mua o 12 mau makahiki i ka hāʻawi ʻana i nā kemika kiʻekiʻe kiʻekiʻe a me nā nanomaterials. Hoʻokuʻu aku ka hui i nā ʻāina he nui e like me USA, Canada, Europe, UAE, South Africa, Tanzania, Kenya, Egypt, Nigeria, Cameroon, Uganda, Turkey, Mexico, Azerbaijan, Belgium, Cyprus, Czech Republic, Brazil, Chile, Dubai, Iapana, Korea, Vietnam, Thailand, Malaysia, Indonesia, Australia, Kelemānia, Palani, Italia, Pokukala, etc.

Ma ke ʻano he mea hana hoʻomohala nanotechnology alakaʻi, ʻo RBOSCHCO ka luna o ka mākeke. Hāʻawi kā mākou hui hana ʻoihana i nā hāʻina kūpono e kōkua i ka hoʻomaikaʻi ʻana i ka pono o nā ʻoihana like ʻole, hana i ka waiwai, a maʻalahi hoʻi i nā pilikia like ʻole.

Inā ʻoe e ʻimi nei iā SiC a me B4C, e ʻoluʻolu e leka uila. ( [email protected] )
