Hoʻopili ʻia ʻo Silicon Carbide
Ua hoʻolālā ʻia nā haku mele silicon carbide i hoʻopaʻa ʻia no ka ikaika maikaʻi loa a me ka pale ʻana i ka corrosion. ʻO nā pōmaikaʻi o ka hoʻohana ʻana i ka reaction bonded silicon carbide e like me: ke kū kūʻokoʻa o ka ʻaʻahu, ke ola lōʻihi ma muli o kona kūpaʻa maikaʻi ʻana i ka oxidation, ke kūpaʻa haʻalulu wela maikaʻi loa, a me nā mana paʻakikī nui a liʻiliʻi paha.
Nitride Silicon Carbide
Hoʻolālā ʻia ʻo Silicon nitride bonded silicon carbide no ke kū kūʻokoʻa o ka lole. Hiki ke hana ʻia i loko o nā ʻano paʻakikī loa ma muli o kāna mau hiʻohiʻona castable a loaʻa pū kekahi i nā waiwai refractory a me nā mea kemika. ʻO kāna hoʻohana mua ʻana ma kahi e pono ai ke kūpaʻa ʻaʻahu kiʻekiʻe loa a i ʻole kahi paʻakikī o ke ʻano no ka hana ʻana i nā hui ʻē aʻe. Loaʻa nō hoʻi nā ʻano hoʻopaʻa ʻelua i loaʻa ʻole ka porosity hāmama a hoʻomaikaʻi i ka pale ʻana i ka oxidation.
Sintered Silicon Carbide
Hoʻokumu ʻia ka carbide alpha silicon sintered e ka sintering ultra-pure submicron powder. Hoʻohui ʻia kēia pauka me nā mea hoʻoheheʻe non-oxide, a laila hana ʻia i mau ʻano paʻakikī e nā ʻano hana like ʻole a hoʻohui ʻia e ka sintering i ka mahana ma luna o 3632°F.
ʻO ke kaʻina hana sintering e loaʻa i kahi carbide silikoni maikaʻi loa i maʻemaʻe loa a ʻaʻahu like ʻole, me ka ʻaneʻane ʻaʻohe porosity e hiki ai i nā mea ke kū i nā kaiapuni corrosive, nā kaiapuni abrasive, a me nā kaiapuni e hana ana ma lalo o ka wela kiʻekiʻe (2552 ° F). Hana kēia mau waiwai i ka alpha silicon carbide i kūpono no nā noi e like me ke kemika a me ka slurry pump sila a me nā bearings, nozzles, pump and valve trim, pepa a me nā mea textile, a me nā mea hou aku.
