Hana like ka silicone carbide me he daimana lā. ʻAʻole wale ia ka mea māmā loa, akā ʻo ia hoʻi ka mea seramika paʻakikī loa a he conductivity thermal maikaʻi loa, hoʻonui wela haʻahaʻa a kūpaʻa loa i nā waikawa a me nā lyes.
Me nā keramika silicon carbide, e mau ana nā waiwai o nā mea a hiki i nā mahana ma luna o 1,400°C. ʻO ke kiʻekiʻe o ka modulus Young > 400 GPa e hōʻoiaʻiʻo ana i ke kūpaʻa maikaʻi loa o ka dimensional. ʻO kēia mau waiwai o nā mea e hoʻolilo i ka silicon carbide i hoʻoholo mua ʻia no ka hoʻohana ʻana ma ke ʻano he mea kūkulu hale. Hoʻokele akamai ʻo Silicon carbide i ka corrosion, abrasion a me ka erosion e like me ke kū ʻana i ka ʻaʻahu frictional. Hoʻohana ʻia nā ʻāpana i nā mea kanu kemika, nā wili, nā mea hoʻonui a me nā extruders a i ʻole ma ke ʻano he nozzles, no ka laʻana.
"Ua hoʻokumu ʻia nā ʻano like ʻole ʻo SSiC (sintered silicon carbide) a me SiSiC (silicon infiltrated silicon carbide). He kūpono loa ka mea hope no ka hana ʻana i nā ʻāpana nui paʻakikī."
He palekana ka Silicon carbide i nā mea ʻawahia a hiki ke hoʻohana ʻia i ka ʻoihana meaʻai. ʻO kekahi noi maʻamau no nā ʻāpana silicon carbide ʻo ia ka ʻenehana sila dynamic e hoʻohana ana i nā bearings friction a me nā sila mechanical, no ka laʻana i nā pumps a me nā ʻōnaehana hoʻokele. Ke hoʻohālikelike ʻia me nā metala, hiki i ka silicon carbide ke hoʻonā i nā hoʻonā waiwai nui me ke ola mea hana lōʻihi ke hoʻohana ʻia me nā media ikaika a kiʻekiʻe. He kūpono hoʻi nā keramika Silicon carbide no ka hoʻohana ʻana i nā kūlana koi i ka ballistics, ka hana kemika, ka ʻenehana ikehu, ka hana pepa a me nā ʻāpana ʻōnaehana paipu.
ʻO ka silicon carbide i hoʻopaʻa ʻia me ka hopena, i ʻike ʻia hoʻi ʻo silicon carbide siliconized a i ʻole SiSiC, he ʻano silicon carbide i hana ʻia e kahi hopena kemika ma waena o ke kalapona porous a i ʻole graphite me ka silicon heheʻe. Ma muli o nā koena i koe o ka silicon, ua kapa pinepine ʻia ka silicon carbide i hoʻopaʻa ʻia me ka hopena he silicon carbide siliconized, a i ʻole kona pōkole SiSiC.
Inā hana ʻia ka silicon carbide maʻemaʻe ma o ka sintering o ka pauka silicon carbide, loaʻa pinepine iā ia nā koena o nā kemika i kapa ʻia ʻo nā mea kōkua sintering, i hoʻohui ʻia e kākoʻo i ke kaʻina hana sintering ma ka ʻae ʻana i nā mahana sintering haʻahaʻa. ʻO kēia ʻano silicon carbide i kapa pinepine ʻia ʻo sintered silicon carbide, a i ʻole i hoʻopōkole ʻia i SSiC.
Loaʻa ka pauka silicon carbide mai ka silicon carbide i hana ʻia e like me ka mea i wehewehe ʻia ma ka ʻatikala silicon carbide.
