Ukusabela Sintered Silicon Carbide Ceramic

 

I-Silicon carbide ceramic yi-ceramic material ene-silicon carbide (SiC) njengengxenye eyinhloko, enamandla amakhulu, ukumelana nokushisa okuphezulu nokumelana nokugqwala, futhi isetshenziswa kabanzi emikhakheni yezimboni.

Inqubo yokukhiqiza ikakhulukazi ihlanganisa ukucindezela okushisayo okushisayo, ukucwilisa okungenangcindezi, ukusabela kwe-sintering nezinye izindlela, ngokulawula izinga lokushisa le-sintering (1450-2450 degree) kanye nokwengeza izithasiselo (njenge-boron carbide, i-alumina) ukuze kuzuzwe ukuminyana.

 

 

 

I-reaction sintered silicon carbide ceramic products inezici ezilandelayo ezivelele:
Izakhiwo ezinhle kakhulu zemishini: Ukuqina okuphezulu kakhulu (isilinganiso se-Mohs esingu-9.0-9.5 esiseduze naleso sedayimane), esinamandla okugoba angama-megapascal angama-400-600, nokugcina amandla aphezulu ngisho nasezingeni lokushisa elingu-1600 degree.

Izici ezivelele zokushisa: Ukusebenza okuphezulu kwe-thermal (120 - 220 W/m·K), i-coefficient yokwandisa ukushisa okuphansi (cishe 4.0×10^{-6}/K), ekwazi ukumelana namazinga okushisa afika ku-1400 - 1600℃, kanye nokumelana okuqinile nokushaqeka kwe-thermal (umehluko wezinga lokushisa ongaphezu kuka-800 degree).

Ukuzinza kwamakhemikhali okuvelele: Imelana nokugqwala kwe-asidi ne-alkali, inokumelana ne-oxidation okuqine kakhulu phakathi kwazo zonke-izicengezi ze-oxide ezingezona ze-oxide, ezifanele indawo ebolayo{1}}nezinga lokushisa eliphezulu.

Ukuqina nokuguquguquka: Ukuqina kungaphezu kokuphindwe ka-10 kobumba obujwayelekile, futhi inezici ze-semiconductor (ngokungafani nezitsha zobumba ezijwayelekile zokuvikela ukushisa), okuyenza ifanelekele izimo zokusebenza ezidlulele.

Ama-ceramics e-silicon carbide, ngenxa yokuqina kwawo okuphezulu, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, ukuguquguquka okuphezulu kokushisa nokumelana okuhle kakhulu nokugqokwa, adlala indima ebalulekile emikhakheni eyahlukene yezimboni. Izicelo eziyinhloko zimi kanje:

I. Izinga Lokushisa Eziphezulu kanye Nemboni Yensimbi
-Iziko lokushisa eliphezulu: Ukukhiqiza iziko lomlilo, izinsimbi, imibhobho yokushisa umlilo, izingxenye ezisekela iziko, njll., ezikwazi ukusebenza ngokuzinzile emazingeni okushisa angaphezu kuka-1600℃.
Izinto ezibambayo: Isetshenziselwa ulayini lwesithando esiqhumayo, izitini ezingabambi, namabhodi okufakwa ngaphakathi, ukumelana nokuguguleka kwezinsimbi ezincibilikisiwe futhi andise kakhulu isikhathi sokuphila kwemishini.
Ukuncibilikiswa kwensimbi: Njengama-deoxidizer okuthuthukisa ukuhlanzeka kwamanzi ensimbi, noma enziwe amasongo okuphambukisa aqhubekayo, amashubhu okuvikela i-thermocouple, okuthuthukisa ukusebenza kahle kokuncibilika.

2. Ukukhiqizwa Kwemishini kanye Nenkambu Yokumelana Nokugqoka
Izingxenye zokuvala: Izindandatho zokuvala zemishini ezisetshenziswa kumaphampu amakhemikhali namaphampu amanzi, ezinokumelana nokugqwala okuphindwe kashumi kwezinsimbi ezijwayelekile, kuthuthukisa kakhulu impilo yesevisi.
Amabhere kanye namathuluzi okusika:{0}}amabheringi anesivinini esiphezulu, amareyili angumhlahlandlela, namathuluzi okusika amboziwe, afanele{1}}izinga lokushisa eliphezulu kanye{2}}nezimo eziphakeme zokulayisha, ukunciphisa ukuguga kwezinto zokusebenza.
Gqoka-amapayipi amelana: Amapayipi ezokuthutha ezimayini, ama-impeller lining, anokumelana nokuguga okuphindwe izikhathi ezingu-5-20 kunezinsimbi ezisansimbi.

3. I-Semiconductor kanye ne-Electronic Industry
Imishini ye-Semiconductor: Ama-disc okugaya, izinto ezilungiswayo zokucutshungulwa kwe-wafer, ukumelana namazinga okushisa aphezulu kanye nokugqwala kwamakhemikhali, okuqinisekisa ukunemba kokucubungula.
Ama-substrates akhipha ukushisa: Ama-substrates akhipha ukushisa kumadivayisi-amandla aphezulu (afana ne-IGBT, i-LED), ane-thermal conductivity engu-270 W/m·K, ethuthukisa ukusebenza kahle kokuqeda ukushisa.
Izingxenye ze-elekthronikhi: Izibambisi zombani,{0}}izinqamuleli ezizwelayo kagesi kagesi, njll., izinto zikagesi ezisebenzisa izici zazo ze-conductivity ezingaqondile.

4. Inkambu Yokuvikela Amakhemikhali Nemvelo
Izinto ezikwazi ukumelana nokubola-: Amavalvu, ama-reactor linings, amapayipi, akwazi ukumelana nama-acid aqinile nezisekelo eziqinile (njenge-concentrated 98% sulfuric acid).
Izinhlelo zokusebenza zemvelo: Izihlungi{0}}ezikhipha intuthu yezinga lokushisa eliphezulu (ezifana nokushiswa kukadoti), izithwali ze-ceramic zekhekheba lezinyosi ze-catalytic for exhaust yezimoto.
Izingxenye zamandla: Izixhumi zamangqamuzana kaphethiloli, izifudumezi zokumunca amandla ashisayo elanga, ezinokumelana nezinga lokushisa okungaphezu kuka-1000 degree.

5. Izinkambu Ezikhethekile nezisafufusa
Imboni yeNuclear: Amashubhu afaka amafutha enuzi, iziqukathi zikadoti, amelana nemisebe ye-neutron kanye namazinga okushisa aphezulu.
Izinto ezingangenwa izinhlamvu: Izitsha zobumba ezingangenwa izinhlamvu ngokwelashwa okuqinile, ezinokuqina okuphezulu nokuminyana okuphansi (3.10-3.15 g/cm³).
Imboni ye-Photovoltaic: Izingxenye zokuthutha uketshezi lwe-polysilicon etching, ukuxazulula ukuguga okuphezulu nezinkinga eziqinile zokugqwala.
I-silicon carbide ceramics ishayela indlela entsha yobuchwepheshe ngamandla amasha (i-hydrogen fuel cell, photovoltaics), ama-semiconductors, kanye-nempahla yokugcina ephezulu, futhi iyizinto ezikhethwayo ezimweni ezimbi kakhulu njengezinga lokushisa eliphezulu, ukugqwala, nokuguga okuphezulu.
