ʻO ke ʻano hana ʻoihana o ka silicon carbide i hoʻoheheʻe ʻia e ka hopena, ʻo ia ke unuhi 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 hoʻomaʻemaʻe ʻia i mau waiwai me nā ʻano hoʻolaha like ʻole o nā ʻāpana ma o ka kuʻi ʻana, ka holoi ʻana i ka waikawa ikaika a me ka alkali, nā lako hoʻokaʻawale magnetic a me ka kānana a i ʻole ka hoʻokaʻawale wai.
ʻElua ʻano maʻamau o ka silicon carbide: ʻeleʻele silicon carbide a me ka ʻōmaʻomaʻo silicon carbide, nona nā mea āpau i ka α-SiC. ① Aia ma kahi o 95% SiC ka ʻeleʻele silicon carbide, a ʻoi aku ka kiʻekiʻe o kona ductility ma mua o ka silicon carbide ʻōmaʻomaʻo, ʻo 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, puaʻa hao a me nā metala makamae. ② Aia ma kahi o 97% ka SiC ma luna o ka silicon carbide ʻōmaʻomaʻo, maikaʻi ka hoʻokala ponoʻī, hoʻohana ʻia ka hapa nui o lākou no ka hana ʻana a me ka hana ʻana i nā mea hana carbide, titanium metal a me nā aniani optical, a hoʻohana ʻia hoʻi no ka honi ʻana i ka liner cylinder a me ka polishing ʻana i nā mea hana kila wikiwiki. Eia kekahi, aia nā mika cubic o ka silicon carbide, he kristal ʻōmaʻomaʻo māmā i hana ʻia e kahi hana hou, a hoʻohana ʻia e hana i kahi ʻano kūpono no ka hali ʻana i ka super-finishing, hiki ke hana i ka ʻili roughness mai Ra32 ~ 0.16μm a i Ra0.04 ~ 0.02μm.
Nā hoʻohana nui o ka hopena sintering silicon carbide
(1) Ma ke ʻano he mea pale i ke komo ʻana, hiki ke hoʻohana ʻia e like me ka mold, e like me ka huila one, ka pōhaku hoʻowali, ka huila wili, ka tile one, a pēlā aku.
(2) Ma ke ʻano he mea hoʻohemo ʻoki a me ka mea pale i ka pala no ka ʻoihana metallurgical. ʻO ka Silicon carbide ka mea nui e komo pū me ʻehā mau hoʻohana nui, ʻo ia hoʻi: nā keramika hana, nā mea refractory kiʻekiʻe, nā mea pale i ka ʻaʻahu a me nā mea maka hoʻoheheʻe. I kēia manawa, hiki ke hoʻolako ʻia ka silicon carbide roughage ma nā ʻano he nui, ʻaʻole ia he huahana ʻenehana kiʻekiʻe, a ʻo ka hoʻohana ʻana i ka pauka nano-silicon carbide me ka ʻike ʻepekema a me ka ʻenehana kiʻekiʻe loa, ʻaʻole paha e hana i nā hopena unahi i ka wā pōkole.
(3) kristal hoʻokahi kiʻekiʻe-maʻemaʻe, kūpono no ka hana ʻana o nā mea semiconductor, ka hana ʻana o nā olonā kemika silicon carbide.
Ka laulā o ke noi: No nā pūnaewele photovoltaic 3-12 kapuaʻi, nā pūnaewele photovoltaic, potassium arsenide, quartz resonators a me nā laina ʻoki ʻē aʻe. ʻO ka ʻoihana photovoltaic solar, ka ʻoihana semiconductor, ka hana ʻenekinia kaulahao ʻoihana kristal piezoelectric.
ʻO ka silicon carbide sintering reactive - nā kumu hoʻokumu
ʻO ke kūlana kiʻekiʻe loa o ke kaomi a me ke kiʻekiʻe o ka mahana i hana ʻia ma ke kikowaena o ka honua ua pīpī ʻia mai ka lepo me ka pele. E like me Thailand, Australia, Shandong o Kina, ʻAmelika Hui Pū ʻIa a me nā ʻāina ʻē aʻe. Hana ʻia ka jade kila ma o ka hoʻopā ʻana i ka metamorphism. E like me Myanmar, Kashmir, Anhui o Kina a me nā wahi ʻē aʻe. Loaʻa nui nā Rubies ma ka honua mai nā placers. Ma o nā ʻano emeralds ecological kumu, nā pōhaku polū ma o ka hopena erosion aggregation sintering silicon carbide me ka silicon ore maoli maʻemaʻe, carbon, wood slag, paʻakai ʻoihana e like me nā mea maka i hana ʻia, i loko o ka hoʻomehana uila umu hoʻomehana i hōʻike ʻia ka hanauna. ʻO ka hoʻohui ʻana o ka slag lāʻau e hana i kahi ʻāpana liʻiliʻi o nā mea i hui ʻia ma ke kiʻekiʻe wela e hana i kahi ʻano porous, kahi e kūpono ai i ka hōʻike ʻana i ke kino mahu nui a me ka volatility mai kahi e wehe ai, e pale i nā pōpilikia pahū, ma muli o ka hanauna o 1 ton o silicon carbide, hiki ke hana ma kahi o 1.4t o carbon monoxide (CO). ʻO ke kuleana o ka paʻakai ʻoihana (NaCl) e kūpono i ka wehe ʻana i ka alumini oxide, nā hui a me nā koena ʻē aʻe i loko o ka mea.
