Hoʻopili hou ʻiakilikaka carbide (RSiC) seramikahe amea kiʻekiʻe-hana keramika. Ma muli o kona kūpaʻa kiʻekiʻe kiʻekiʻe loa, ka pale ʻana i ka oxidation, ka pale ʻana i ka corrosion a me ka paʻakikī kiʻekiʻe, ua hoʻohana nui ʻia ia ma nā ʻano he nui, e like me ka hana semiconductor, ʻoihana photovoltaic, nā umu wela wela a me nā mea hana kemika. Me ka piʻi nui ʻana o ka noi no nā mea hana kiʻekiʻe i ka ʻoihana hou, ʻo ka noiʻi ʻana a me ka hoʻomohala ʻana o ka recrystallized silicon carbide ceramics e hohonu ana.
1. Hoʻomākaukau 'enehana onā mea hoʻoheheʻe kiʻekiʻe kiʻekiʻe
ʻO ka ʻenehana hoʻomākaukau o recrystallizedsilika carbide seramikaʻO ka nui o nā ʻano ʻelua: ka pauka sintering a me ka vapor deposition (CVD). Ma waena o lākou, ʻo ke ʻano o ka pauka sintering ʻo ia ka sinter silicon carbide pauka ma lalo o ke kiʻekiʻe o ka mahana wela i mea e hana ai nā ʻāpana silicon carbide i kahi ʻano paʻa ma o ka diffusion a me ka recrystallization ma waena o nā kīʻaha. ʻO ke ʻano o ka hoʻoheheʻe ʻana i ka mahu, ʻo ia ka waiho ʻana i ka silicon carbide ma luna o ka ʻili o ka substrate ma o ka hopena vapor chemical i ka wela kiʻekiʻe, a laila e hana ai i kahi kiʻiʻoniʻoni silicon carbide kiʻekiʻe a i ʻole nā ʻāpana kūkulu. Loaʻa i kēia mau ʻenehana ʻelua ko lākou pono ponoʻī. He kūpono ke ʻano o ka pauka sintering no ka hana nui a me ke kumu kūʻai haʻahaʻa, ʻoiai ke ʻano o ka deposition vapor hiki ke hāʻawi i ka maʻemaʻe kiʻekiʻe a me ka hoʻolālā ʻoi aku ka nui, a hoʻohana nui ʻia i ke kahua semiconductor.
2. Mea waiwai onā mea hoʻoheheʻe kiʻekiʻe kiʻekiʻe
ʻO ka hiʻohiʻona koʻikoʻi o ka recrystallized silicon carbide ceramics ʻo ia kāna hana maikaʻi loa i nā wahi wela kiʻekiʻe. ʻO ka helu hoʻoheheʻe o kēia mea he kiʻekiʻe e like me 2700 ° C, a he ikaika mechanical maikaʻi kona i nā mahana kiʻekiʻe. Eia kekahi, ʻoi aku ka maikaʻi o ka recrystallized silicon carbide a me ka pale ʻana i ka corrosion, a hiki ke noho paʻa i nā wahi kemika koʻikoʻi. No laila, ua hoʻohana nui ʻia nā ceramics RSiC i nā kula o nā umu wela wela, nā mea refractory kiʻekiʻe, a me nā mea hana kemika.
Eia kekahi, loaʻa i ka carbide silicon recrystallized kahi conductivity thermal kiʻekiʻe a hiki ke hana maikaʻi i ka wela, kahi e loaʻa ai ka waiwai noi nui i loko.ʻO nā mea hoʻoheheʻe MOCVDa me nā lako hoʻomaʻamaʻa wela i ka hana wafer semiconductor. ʻO kāna conductivity thermal kiʻekiʻe a me ke kūpaʻa haʻalulu wela e hōʻoia i ka hana hilinaʻi o nā mea hana ma lalo o nā kūlana koʻikoʻi.
3. Noi na kahua o recrystallized silika carbide seramika
Hana Semiconductor: Ma ka ʻoihana semiconductor, hoʻohana ʻia nā seramika silicon carbide recrystallized e hana i nā substrates a me nā kākoʻo i nā reactors MOCVD. Ma muli o kona kūpaʻa kiʻekiʻe o ka wela, ka pale ʻana i ka corrosion, a me ka conductivity thermal kiʻekiʻe, hiki i nā mea RSiC ke hoʻomau i ka hana paʻa i loko o nā kaiapuni kūlohelohe paʻakikī, e hōʻoia ana i ka maikaʻi a me ka hua o nā wafers semiconductor.
ʻOihana Photovoltaic: Ma ka ʻoihana photovoltaic, hoʻohana ʻia ʻo RSiC e hana i ke ʻano kākoʻo o nā lako ulu kristal. No ka mea, pono e hoʻokō ʻia ka ulu ʻana o ka kristal i ka wela kiʻekiʻe i ka wā o ka hana ʻana o nā cell photovoltaic, ʻo ke kūpaʻa wela o ka recrystallized silicon carbide e hōʻoia i ka hana paʻa o nā mea hana.
Nā kapuahi wela kiʻekiʻe: Hoʻohana nui ʻia nā ceramics RSiC i nā umu wela kiʻekiʻe, e like me nā linings a me nā ʻāpana o nā umu, nā umu hoʻoheheʻe a me nā mea hana ʻē aʻe. ʻO kona kūpaʻa haʻalulu wela a me ke kūpaʻa oxidation e lilo ia i mea hoʻololi ʻole i nā ʻoihana kiʻekiʻe.
4. Ke kuhikuhi noiʻi o recrystallized silikon carbide seramika
Me ka piʻi nui ʻana o ka noi no nā mea hana kiʻekiʻe, ʻo ke kuhikuhi noiʻi o recrystallized silicon carbide ceramics ua akaka iki. E kālele ana ka noiʻi e hiki mai ana i kēia mau ʻaoʻao:
Hoʻomaikaʻi i ka maʻemaʻe waiwai: I mea e hoʻokō ai i nā koi maʻemaʻe kiʻekiʻe ma ka semiconductor a me nā kiʻi photovoltaic, ke ʻimi nei nā mea noiʻi i nā ala e hoʻomaikaʻi ai i ka maʻemaʻe o RSiC ma o ka hoʻomaikaʻi ʻana i ka ʻenehana deposition mahu a i ʻole ka hoʻokomo ʻana i nā mea maka hou, a laila e hoʻonui ai i kāna waiwai noi i kēia mau kula kiʻekiʻe. .
Hoʻonui i ka microstructure: Ma ka hoʻomalu ʻana i nā kūlana sintering a me ka hāʻawi ʻana i nā ʻāpana pauka, hiki ke hoʻomaikaʻi hou ʻia ka microstructure o recrystallized silicon carbide, a laila e hoʻomaikaʻi ai i kāna mau waiwai mechanical a me ke kūpaʻa haʻalulu wela.
Nā mea hana i hui pū ʻia: I mea e hoʻololi ai i nā kaiapuni hoʻohana ʻoi aku ka paʻakikī, ke hoʻāʻo nei nā mea noiʻi e hoʻohui i ka RSiC me nā mea ʻē aʻe e hoʻomohala i nā mea i hoʻohui ʻia me nā waiwai multifunctional, e like me ka recrystallized silicon carbide-based composite material me ka ʻoi aku o ke kūpaʻa aahu a me ka conductivity uila.
5. Ka hopena
Ma ke ʻano he mea hana kiʻekiʻe, ua hoʻohana nui ʻia nā ceramics silicon carbide recrystallized i nā kula he nui ma muli o ko lākou mau waiwai maikaʻi loa i ke kiʻekiʻe kiʻekiʻe, ke kūpaʻa o ka oxidation a me ke kūpaʻa corrosion. E kālele ana ka noiʻi ʻana i ka wā e hiki mai ana i ka hoʻomaikaʻi ʻana i ka maʻemaʻe waiwai, ka hoʻonui ʻana i ka microstructure a me ka hoʻomohala ʻana i nā mea hana composite e hoʻokō i nā pono ʻoihana ulu. Ma o kēia mau hana ʻenehana, ua manaʻo ʻia ka recrystallized silicon carbide ceramics e pāʻani i kahi ʻoi aku ka nui o nā kula kiʻekiʻe.
