Toe fa'a'aisasilikon carbide (RSiC) keramikao amea sima maualuga-faatinoga. Ona o lona maualuga maualuga maualuga teteʻe, oxidation tetee, corrosion teteʻe ma maualuga maaa, ua faʻaaogaina lautele i le tele o fanua, e pei o semiconductor gaosiga, alamanuia photovoltaic, ogaumu vevela maualuga ma meafaigaluega vailaau. Fa'atasi ai ma le fa'ateleina o le mana'omia mo mea e fa'atino maualuga i alamanuia fa'aonaponei, o lo'o fa'alolotoina le su'esu'ega ma le atina'eina o sima carbide silicon recrystallized.
1. Sauniuniga tekinolosi ofa'amea fa'ama'i fa'ama'i fa'ama'i fa'ama'i carbide keramika
Le tekinolosi sauniuniga o recrystallizedsilicon carbide ceramicse masani ona aofia ai auala e lua: fa'amama pa'u ma le fa'afu ausa (CVD). Faatasi ai ma i latou, o le auala sintering paʻu o le sinter silicon carbide paʻu i lalo o le maualuga vevela siosiomaga ina ia silicon carbide particles fausia se fausaga mafiafia e ala i diffusion ma recrystallization i le va o fatu. O le auala e teu ai ausa o le teuina lea o le carbide silicon i luga o le substrate e ala i se tali ausa vailaʻau i le maualuga o le vevela, ma faʻatupuina ai se ata tifaga carbide silikoni mama-maualuga poʻo vaega faʻavae. O nei tekinolosi e lua e iai o latou lava lelei. O le auala sintering paʻu e talafeagai mo le gaosiga tele ma e maualalo le tau, aʻo le faʻaogaina o le ausa e mafai ona maua ai le mama maualuga ma le faʻapipiʻiina o le fausaga, ma e faʻaaogaina lautele i le semiconductor field.
2. Meafaitino ofa'amea fa'ama'i fa'ama'i fa'ama'i fa'ama'i carbide keramika
O le uiga mata'ina o keramika carbide silicon recrystallized o lona faatinoga sili ona lelei i siosiomaga vevela maualuga. O le mea faʻafefeteina o lenei mea e maualuga atu i le 2700 ° C, ma e iai le malosi faʻainisinia lelei i le maualuga o le vevela. E le gata i lea, o le carbide silicon recrystallized foi e sili ona lelei le faʻamaʻiina o le faʻamaʻiina ma le faʻamaʻiina o le corrosion, ma e mafai ona tumau mautu i siosiomaga faʻamaʻi ogaoga. O le mea lea, RSiC ceramics ua faʻaaogaina lautele i fanua o ogaumu vevela maualuga, mea faʻafefete maualuga-vevela, ma masini vailaʻau.
E le gata i lea, o le carbide silicon recrystallized o loʻo i ai le maualuga o le faʻaogaina o le vevela ma e mafai ona faʻaleleia lelei le vevela, lea e maua ai le taua tele o le faʻaaogaina i totonu.MOCVD reactorsma mea e fa'aogaina ai le vevela i le gaosiga o le semiconductor wafer. O lona maualuga maualuga o le vevela ma le teteʻe o le vevela e mautinoa ai le faʻatuatuaina o le faʻaogaina o meafaigaluega i lalo o tulaga ogaoga.
3. Fa'aoga fanua o fa'amea fa'ama'i fa'ama'i fa'amea fa'ameamea
gaosiga semiconductor: I totonu o le semiconductor alamanuia, recrystallized silicon carbide ceramics e faʻaaogaina e gaosia ai substrates ma lagolago i reactors MOCVD. Ona o le maualuga o le vevela, teteʻe o le corrosion, ma le maualuga o le vevela, e mafai e mea RSiC ona faʻamautu le faʻatinoina o faʻatinoga i totonu o siosiomaga faʻalavelave faʻalavelave faʻalavelave, faʻamautinoaina le lelei ma le gaosiga o semiconductor wafers.
Alamanuia Photovoltaic: I totonu o le alamanuia photovoltaic, RSiC faʻaaogaina e gaosia ai le fausaga lagolago o meafaigaluega tuputupu aʻe tioata. Talu ai ona o le tuputupu aʻe tioata e manaʻomia ona faʻatinoina i le maualuga o le vevela i le taimi o le gaosiga o le gaosiga o sela photovoltaic, o le faʻafefe o le vevela o le carbide silicon recrystallized e faʻamautinoa ai le faʻaogaina o meafaigaluega mo se taimi umi.
Ogaumu vevela maualuga: RSiC ceramics o loʻo faʻaaogaina lautele i ogaumu vevela maualuga, e pei o linings ma vaega o ogaumu mama, ogaumu liusuavai ma isi meafaigaluega. O lona tete'e te'i vevela ma le fa'ama'iina fa'ama'i ua avea ai ma se tasi o mea e le mafai ona fa'aaogaina i alamanuia maualuga-vevela.
4. Fa'atonuga su'esu'e o sima carbide recrystallized
Fa'atasi ai ma le fa'atupula'ia o mana'oga mo meafaitino maualuga, o le su'esu'ega o su'esu'ega o fa'amea fa'amea fa'ameamea ua fa'asolosolo malie ua manino. O suʻesuʻega i le lumanaʻi o le a taulaʻi i vaega nei:
Faʻaleleia le mama o meafaitino: Ina ia faʻamalieina manaʻoga maualuga atu i le semiconductor ma photovoltaic fields, o loʻo suʻesuʻeina e le au suʻesuʻe auala e faʻaleleia ai le mama o le RSiC e ala i le faʻaleleia atili o tekinolosi faʻapipiʻi ausa poʻo le faʻalauiloaina o mea fou fou, ma faʻaleleia ai lona aoga aoga i nei matata tekonolosi. .
Optimizing microstructure: E ala i le pulea o tulaga sintering ma le tufatufaina atu o vaega o le paʻu, o le microstructure o recrystallized silicon carbide e mafai ona sili atu optimized, faʻapea le faʻaleleia o ona mea faʻainisinia ma faʻalavelave faʻafuaseʻi.
Mea fa'aoga tu'ufa'atasiga: Ina ia fa'afetaui i si'osi'omaga fa'aoga lavelave, o lo'o taumafai tagata su'esu'e e tu'ufa'atasia le RSiC ma isi mea e atia'e ai mea tu'ufa'atasi ma mea e tele galuega, e pei o mea fa'apipi'i fa'ameamea fa'avae silicon carbide ma maualuga atu le ofuina ma le fa'agaioia eletise.
5. Fa'ai'uga
I le avea o se mea maualuga-faatinoga, recrystallized silicon carbide ceramics ua faʻaaogaina lautele i le tele o fanua ona o latou meatotino lelei i le maualuga o le vevela, faʻamaʻi faʻamaʻi ma le faʻamaʻi. O su'esu'ega i le lumana'i o le a taula'i atu i le fa'aleleia atili o le mama o meafaitino, fa'asilisiliina o le microstructure ma le atina'eina o mea fa'atino tu'ufa'atasia e fa'afetaui ai mana'oga fa'aolaola. E ala i nei mea fa'atekonolosi fa'atekonolosi, ua fa'amoemoeina e sili atu le sao o mea fa'atekonolosi ua toe fa'ama'aina ile silicon carbide i le tele o fanua fa'atekonolosi.
