ʻO ka seramika Silicon Carbide

ʻO ka Silicon Carbide i hoʻopaʻa ʻia

Ua hoʻolālā ʻia nā hui ʻana o ka silicon carbide i hoʻopaʻa ʻia no ka ikaika kūpono a me ke kūpaʻa i ka pala. ʻO nā pono o ka hoʻohana ʻana i ka silicon carbide i hoʻopaʻa ʻia: ke kūpaʻa ʻana i ka ʻaʻahu, ke ola lōʻihi ma muli o kona kūpaʻa maikaʻi loa i ka oxidation, ke kūpaʻa haʻalulu wela maikaʻi loa, a me nā hiki ke ʻano paʻakikī nui a liʻiliʻi paha.

ʻO ka Nitride Bonded Silicon Carbide

Ua hoʻolālā ʻia ka silicon carbide i hoʻopaʻa ʻia me ka silicon nitride no ke kūpaʻa ʻana i ka ʻaʻahu. Hiki ke hoʻokumu ʻia i loko o nā ʻano paʻakikī loa ma muli o kona mau ʻano hiki ke hoʻoheheʻe ʻia a he mau waiwai refractory a me nā kemika i makemake ʻia. ʻO kona hoʻohana mua ʻana ma kahi e pono ai ke kūpaʻa ʻaʻahu kiʻekiʻe loa a i ʻole kahi paʻakikī loa ke ʻano e hana ai i nā hui ʻē aʻe. Loaʻa pū kekahi mau mana i puhi ʻia i pālua ʻia me ka porosity hāmama liʻiliʻi a me ke kūpaʻa oxidation i hoʻomaikaʻi ʻia.

ʻO ka Carbide Silicon Sintered

Hoʻopuka ʻia ka sintered alpha silicon carbide ma o ka sintering ultra-pure submicron powder. Hoʻohui ʻia kēia pauka me nā mea kōkua sintering non-oxide, a laila hana ʻia i loko o nā ʻano paʻakikī e nā ʻano hana like ʻole a hoʻopaʻa ʻia ma o ka sintering ma ka mahana ma luna o 3632°F.

ʻO ka hopena o ke kaʻina hana sintering he silicon carbide fine-grained hoʻokahi-paepae i maʻemaʻe loa a like, me ka ʻaneʻane ʻole o ka 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 ke ana wela kiʻekiʻe (2552°F). ʻO kēia mau waiwai e hana i ka sintered alpha silicon carbide i kūpono no nā noi e like me nā sila a me nā bearings pamu kemika a me ka slurry, nā nozzles, ka pamu a me ka valve trim, nā ʻāpana pepa a me nā lole, a me nā mea hou aku.
