ʻO ka Silicon carbide he mea hoʻohui kristal o ke silika a me ke kalapona e ka hana synthetic. Ua hoʻohana lōʻihi ʻia ma ke ʻano he mea koʻikoʻi no ka wili ʻana i nā huila a me nā mea ʻoki ʻoki no kona ʻoi loa. ʻO ka mea hou aku nei, loaʻa iā ia kahi hoʻohana ākea i nā ʻāpana pale ʻaʻahu no nā pamu, nā kaʻa, nā mīkini mea kanu a me nā ʻenekinia, i nā linings refractory a me nā mea hoʻomehana no nā kapuahi ʻenehana, i nā ʻāpana haʻalulu wela i nā mīkini rocket. ʻO ka Silicon carbide ka paʻakikī kiʻekiʻe loa ma waena o nā mea synthetic i ʻike ʻia, a hiki i ka paʻakikī Mohs i ka helu o 9, kokoke i ka daimana. ʻO kona conductivity thermal kiʻekiʻe, me kona ikaika wela kiʻekiʻe, hoʻonui haʻahaʻa wela, a me ke kū'ē ʻana i ka hopena kemika, e waiwai ai ka silicon carbide i ka hana ʻana i nā pōhaku kiʻekiʻe-mehana a me nā refractory ʻē aʻe.

He mea koʻikoʻi ka ʻaʻahu a me ka corrosion o nā ʻāpana mechanical no nā mīkini mea kanu no ka mea he hopena nui lākou i ke kumu kūʻai o ka hana. ʻO nā mīkini mea kanu a i ʻole nā ​​​​mea hana e lawe a hoʻoheheʻe i nā mea abrasive, acid a alkali paha i koi ikaika i ka pale ʻana i ka corrosion a me nā waiwai kūʻē abrasion o nā ʻāpana mechanical, e like me nā mea i hoʻohana ʻia i ka kemika, nā meaʻai a me nā mea inu a me nā ʻoihana lāʻau. ʻO ka hopena ceramics kiʻekiʻe no kēlā mau mīkini a i ʻole nā ​​​​mea hana e hōʻoia i ka lōʻihi o ke ola lawelawe, haʻahaʻa ke kumukūʻai mālama a no laila ʻoi aku ka maikaʻi o ka ʻoihana.

Hoʻonohonoho ʻia ʻo ia ma ke ʻano he semiconductor, loaʻa kahi conductivity uila ma waena o nā metala a me nā mea insulating. ʻO kēia waiwai, i hui pū ʻia me kāna mau mea wela, e hoʻolilo iā SiC i mea hoʻohiki e pani ai no nā semiconductor kuʻuna e like me ke silika i nā noi wela kiʻekiʻe.

Nā waiwai o Silicon Carbide (SSiC / SSiC)

ʻAno haʻahaʻa (3.07 a 3.15 g/cm3)

Paʻakiki kiʻekiʻe (HV10 ≥ 22 Gpa)

ʻO ka modulus High Young (380 a 430 Mpa)

ʻO ke kau wela wela kiʻekiʻe (120 a 200 W/mK)

Ka helu haʻahaʻa o ka hoʻonui laina
(3.6 a 4.1x10-6/K ma 20 a 400°C)

ʻO ka wela hana kiʻekiʻe loa o SSiC ma lalo o ke kinoea inert: 1,800°C

Kūleʻa haʻalulu wela maikaʻi loa o SSiC: ΔT 1,100 K
