1, Hoʻopili ʻia i nā mea pōhaku makamae
I loko o ka ʻoihana pōhaku makamae, ʻike ʻia hoʻi ka silicon carbide ʻo "moissanite". ʻO nā mea i ʻike pinepine ʻia ma ka mākeke he moissanite i hana ʻia me ke akamai, ʻoiai he mea kakaikahi loa ka moissanite kūlohelohe, no laila ua ʻike wale ʻia i loko o nā lua meteorite 50000 mau makahiki i hala.
2, Nā noi ʻoihana kuʻuna
Ma ke kahua ʻoihana kuʻuna, hoʻohana nui ʻia ka silicon carbide ma ke ʻano he mea refractory, mea hana abrasive, a me nā mea metallurgical, kahi e loiloi ʻokoʻa ʻia ma ka kikokikona aʻe.
（1） Nā huahana pale wela kiʻekiʻe:
Ke hoʻohana nei i nā ʻano o ke kūpaʻa ʻana i ka pala, ke kūpaʻa wela kiʻekiʻe, ka ikaika kiʻekiʻe, ka conductivity thermal maikaʻi, a me ke kūpaʻa hopena o nā mea silicon carbide, hiki ke hoʻohana ʻia no nā ʻano uhi umu hoʻoheheʻe like ʻole, nā ʻāpana umu wela kiʻekiʻe, nā papa silicon carbide, nā papa uhi, nā kākoʻo, a me nā ladles. Ma ka ʻaoʻao ʻē aʻe, hiki ke hoʻohana ʻia nā mea hoʻomehana pololei ʻole wela kiʻekiʻe i ka ʻoihana hoʻoheheʻe metala non-ferrous, e like me nā umu distillation vertical, nā papa arc no nā umu pauka zinc, nā paipu pale thermocouple, a pēlā aku; Hoʻohana ʻia no ka hana ʻana i nā mea seramika silicon carbide holomua i kūpaʻa i ke kapa komo, kūpaʻa i ka palaho, a kūpaʻa i ke wela kiʻekiʻe; Hiki ke hoʻohana ʻia e hana i nā nozzles rocket, nā pahi turbine kinoea, a pēlā aku. Eia kekahi, ʻo silicon carbide kekahi o nā mea kūpono no nā mea hoʻomehana wai solar ma nā alaloa, nā ala holo mokulele, a pēlā aku. No laila, he inoa maʻamau ko silicon carbide ʻo "sand refractory", ʻoiai he mea maʻamau loa, hōʻike piha i kona mau waiwai refractory.
（2）Nā huahana kūpaʻa i ke komo ʻana a me nā huahana kūpaʻa i ka pala:
ʻO ke kumu nui, no ka mea he paʻakikī kiʻekiʻe ka silicon carbide, me ka paʻakikī Mohs o 9.2-9.8, ʻo ia ka lua ma hope o ke daimana paʻakikī loa o ka honua (pae 10), ua ʻike nui ʻia ʻo ia he "one kila gula". Loaʻa iā ia ke kūpaʻa kemika maikaʻi a me kekahi paʻakikī, a hiki ke hoʻohana ʻia e hana i nā huila wili, nā pepa one, nā kāʻei one, nā pōhaku ʻaila, nā poloka wili, nā poʻo wili, nā mea wili, a no ka wili ʻana a me ka poli ʻana i ka silicon monocrystalline, polycrystalline silicon, a me nā kristal piezoelectric i ka ʻoihana uila i nā huahana optical.
（3）Nā mea maka hao:
Hiki ke hoʻohana ʻia ka Silicon carbide ma ke ʻano he deoxidizer no ka hana kila a me kahi mea hoʻololi no ka hoʻolālā hao i hoʻolei ʻia. Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka hana ʻana i ka silicon tetrachloride a ʻo ia ka mea maka nui no ka ʻoihana resin silicone. ʻO ka Silicon carbide deoxidizer kahi ʻano hou o ka deoxidizer composite ikaika e pani ana i ka pauka silicon kuʻuna a me ka pauka kalapona no ka deoxidation. Ke hoʻohālikelike ʻia me ke kaʻina hana mua, ʻoi aku ka paʻa o nā waiwai kino a me nā kemika, ka hopena deoxidation maikaʻi, ka manawa deoxidation pōkole, ka ikehu i mālama ʻia, ka hoʻomaikaʻi ʻana i ka pono o ka hana kila, ka hoʻomaikaʻi ʻana i ke ʻano kila, ka hoʻemi ʻana i ka hoʻohana ʻana i nā mea maka, ka hoʻemi ʻana i ka haumia o ke kaiapuni, nā kūlana hana i hoʻomaikaʻi ʻia, a me ka hoʻonui ʻana i nā pono waiwai piha o nā umu uila, he waiwai nui nā mea a pau.
3, mea hoʻomālamalama ʻōlinolino silikona carbide
ʻO nā mea seramika i hana ʻia me ka hoʻohana ʻana i nā hana kūikawā o nā seramika ma ke ʻano o nā waiwai kino e like me ke kani, ka mālamalama, ka uila, ka magnetism, a me ka wela ua kapa ʻia he keramika hana. Nui nā ʻano keramika hana me nā hoʻohana like ʻole, a hoʻohana nui ʻia ka silicon carbide ma ke ʻano he mea aniani noʻonoʻo i ke kahua o nā keramika hana. Loaʻa i nā keramika SiC ke kiʻekiʻe o ka paʻakikī kikoʻī, ka paʻa wela a me ke kemika maikaʻi, ka coefficient deformation thermal haʻahaʻa, a me ke kūʻē ʻana i ka irradiation particle space. Ma o nā kaʻina hana hana kūikawā, hiki ke loaʻa nā kino aniani māmā.
4. Ma ke ʻano he mea semiconductor
ʻO ka semiconductor hanauna ʻekolu kahi mea koʻikoʻi nui a me ka ʻāpana uila e kākoʻo ana i ka hana hou, hoʻomohala, hoʻololi a me ka hoʻomaikaʻi ʻana i nā mea kaua pale aupuni, nā kamaʻilio kelepona 5G, ka Pūnaewele ikehu, nā kaʻa ikehu hou, ka halihali kaʻaahi a me nā ʻoihana ʻē aʻe. Ma muli o kona kuleana koʻikoʻi i ka palekana pale aupuni, ka hana akamai, ka hoʻomaikaʻi ʻana i ka ʻoihana, ka mālama ʻana i ka ikehu a me ka hoʻemi ʻana i ka hoʻokuʻu ʻana a me nā pono koʻikoʻi ʻē aʻe, ke lilo nei ia i wahi kauoha loea o ka hoʻokūkū ma ka honua.
ʻO SiC, ma ke ʻano he ʻelele maʻamau o nā mea semiconductor hanauna ʻekolu, ʻo ia kekahi o nā mea semiconductor bandgap ākea i hoʻohana nui ʻia a hoʻohana nui ʻia i ka ʻenehana hana kristal a me ka hana ʻana i nā mea hana. Ua hoʻokumu ia i kahi kaulahao ʻoihana mea, mea hana, a me nā noi honua. He mea semiconductor kūpono ia no nā noi wela kiʻekiʻe, alapine kiʻekiʻe, pale i ka radiation, a me ka mana kiʻekiʻe. Ma muli o ka emi nui ʻana o ka hoʻohana ʻana i ka ikehu o nā mea uila, ua ʻike ʻia nā mea mana silicon carbide ʻo ia nā "mea ikehu ʻōmaʻomaʻo" e hoʻokele ana i ka "kipi ikehu hou".
5, Mea hoʻoikaika a hoʻopaʻakikī
Ma waho aʻe o nā noi i luna, ua hoʻohana nui ʻia nā ʻumiʻumi silicon carbide a i ʻole nā lohi silicon carbide ma ke ʻano he mea hoʻoikaika maikaʻi loa a me nā mea hoʻoikaika i nā mea i hui pū ʻia me nā mea metala a i ʻole nā mea seramika i nā kahua e like me ka mīkini, ka ʻenekinia kemika, ka pale kaua aupuni, ka ikehu, a me ka palekana o ke kaiapuni.
