ʻO ke ʻano hana ʻenehana o ka reaction-sintered silicon carbide ʻo ia ka lawe ʻana i ke one quartz kiʻekiʻe a me ka coke petroleum calcined i loko o kahi umu hoʻomehana uila. Hana ʻia nā poloka silicon carbide i mau mea kūʻai me nā ʻāpana like ʻole o ka nui o nā ʻāpana e ka ʻoki ʻana, ka wai ikaika a me ka holoi alkali, nā mea hana hoʻokaʻawale magnetic a me ka nānā ʻana a i ʻole ka hoʻokaʻawale wai.
ʻElua ʻano maʻamau maʻamau o ka carbide silikoni ʻeleʻele a me ka carbide silicon ʻōmaʻomaʻo, aia nā mea āpau i ka α-SiC. ① Loaʻa ka carbide silicon ʻeleʻele ma kahi o 95% SiC, a ʻoi aku ka kiʻekiʻe o kona ductility ma mua o ka carbide silicona ʻōmaʻomaʻo, ka hapa nui o ia mau mea e hoʻohana ʻia e hana a hana i nā mea maka me ka ikaika tensile haʻahaʻa, e like me ke aniani laminated, porcelain, pōhaku, refractory, hao puaʻa a metala makamae. ② Loaʻa i ka carbide silicon green ka SiC ma kahi o 97% ma luna, maikaʻi ka hoʻomaʻamaʻa ponoʻī, hoʻohana ʻia ka hapa nui o lākou no ka hana ʻana a me ka hana ʻana i nā mea hana carbide, titanium metala a me nā lens optical, a hoʻohana ʻia hoʻi no ka honing cylinder liner a me ka polishing kiʻekiʻe. mea kila. Eia kekahi, aia nā mika cubic o ka silicon carbide, he aniani ʻōmaʻomaʻo māmā i hana ʻia e kahi kaʻina hana hou, a hoʻohana ʻia e hana i kahi mold kūpono no ka lawe ʻana i ka super-finishing, hiki ke hana i ka ʻili o ka ʻili mai Ra32 ~ 0.16μm i ka hana. i Ra0.04 ~ 0.02μm.
ʻO ka hoʻohana nui ʻana o ka carbide sintering silika
(1) Ma ke ʻano he mea ʻaʻahu, hiki ke hoʻohana ʻia e like me ka mold, e like me ka huila one, whetstone, grinding wheel, sand tile, etc.
(2) Ma ke ʻano he mea hoʻoheheʻe deoxidizing a me nā mea pale corrosion no ka ʻoihana metallurgical. Hoʻohana nui ʻia ʻo Silicon carbide i ʻehā mau hoʻohana nui, ʻo ia hoʻi: nā seramika hana, nā mea refractory kiʻekiʻe kiʻekiʻe, nā mea pale lole a me ka hoʻoheheʻe ʻana i nā mea maka. I kēia manawa, hiki ke hoʻolako ʻia ka silicon carbide roughage ma nā ʻano he nui, ʻaʻole ia he huahana kiʻekiʻe, a ʻo ka hoʻohana ʻana i ka pauka nano-silicon carbide me ka ʻike ʻepekema a me ka ʻenehana kiʻekiʻe ʻaʻole hiki ke hana i nā hopena pālākiō i ka wā pōkole.
(3) kiʻekiʻe-maʻemaʻe hoʻokahi aniani, kūpono no ka hana ʻana i nā mea semiconductor, ka hana ʻana i nā fiber chemical carbide silicon.
Ka laulā o ka noi: No 3-12 kapuaʻi kiʻi kiʻi kiʻi kiʻi, kiʻi kiʻi kiʻi kiʻi, potassium arsenide, quartz resonator a me nā laina laina ʻē aʻe. ʻOihana photovoltaic solar, ʻoihana semiconductor, piezoelectric crystal chain chain engineering project raw material processing.
ʻO ka carbide silika hoʻoheheʻe reactive - nā kumu hoʻokumu
ʻO ka puʻe kiʻekiʻe kiʻekiʻe a me ka maʻamau wela kiʻekiʻe i hana ʻia i loko o ke kumu o ka honua i kāpī ʻia mai ka lepo me ka pele. E like me Thailand, Australia, Kina Shandong, ʻAmelika Hui Pū ʻIa a me nā ʻāina ʻē aʻe. Hoʻokumu ʻia ka jade kila e ka paʻi metamorphism. E like me Myanmar, Kashmir, Kina Anhui a me nā wahi ʻē aʻe. Loaʻa ka nui o nā rubi ma ka honua mai nā mea hoʻonoho. ʻO ia ma o nā ʻano o nā emeralds ecological maoli, nā pōhaku uliuli e ka erosion aggregation reaction sintering silicon carbide me ka maʻemaʻe maoli silicon ore, carbon, slag lāʻau, paʻakai ʻoihana e like me ka mea i hoʻokumu ʻia i nā mea maka, i ka umu hoʻomehana uila i hōʻike ʻia. ʻO ka hoʻohui ʻana o ka lāʻau slag e hana i kahi ʻāpana liʻiliʻi o nā mea i hui ʻia i ka wela kiʻekiʻe e hana i kahi hale porous, kahi kūpono e hōʻike i ke kino mahu nui a me ka volatility kahi e wehe ai, e pale ai i nā pōpilikia pahū, ma muli o ka hanauna. o 1 tona o ke kalapona kalapona, hiki ke hana ma kahi o 1.4t kalapona monoxide (CO). ʻO ke kuleana o ka paʻakai ʻoihana (NaCl) he mea kūpono i ka wehe ʻana i ka alumini oxide, nā pūhui a me nā koena ʻē aʻe i loko o ka mea.
